The programme for the segmentation of a speech into fonems was created as a part of the master´s thesis. This programme was made in the programme Matlab and consists of several scripts. The programme serves for automatic segmentation. Speech segmentation is the process of identifying the boundaries between phonemes in spoken natural languages. Automatic segmentation is based on vector quantization. In the first step of algorithm, feature extraction is realized. Then speech segments are assigned to calculated centroids. Position where centroid is changed is marked as a boundary of phoneme. The audiorecords were elaborated by the programme and a operation of the automatic segmentation was analysed. A detailed manual was created to the programme too. Individual used methods of the elaboration of a speech were in the master´s thesis briefly descripted, its implementations in the programme and reasons of set of its parameters.

Cette thèse de doctorat aborde les problématiques de l'estimation de confiance pour la traduction automatique, et de la traduction automatique statistique de la parole spontanée à grand vocabulaire. J'y propose une formalisation du problème d'estimation de confiance, et aborde expérimentalement le problème sous le paradigme de la classification et régression multivariée. Je propose une évaluation des performances des différentes méthodes évoquées, présente les résultats obtenus lors d'une campagne d'évaluation internationale et propose une application à la post-édition par des experts de documents traduits automatiquement. J'aborde ensuite le problème de la traduction automatique de la parole. Après avoir passé en revue les spécificités du medium oral et les défis particuliers qu'il soulève, je propose des méthodes originales pour y répondre, utilisant notamment les réseaux de confusion phonétiques, les mesures de confiances et des techniques de segmentation de la parole. Je montre finalement que le prototype propose rivalise avec des systèmes état de l'art à la conception plus classiqueIn this thesis I shall deal with the issues of confidence estimation for machine translation and statistical machine translation of large vocabulary spontaneous speech translation. I shall first formalize the problem of confidence estimation. I present experiments under the paradigm of multivariate classification and regression. I review the performances yielded by different techniques, present the results obtained during the WMT2012 internation evaluation campaign and give the details of an application to post edition of automatically translated documents. I then deal with the issue of speech translation. After going into the details of what makes it a very specific and particularly challenging problem, I present original methods to partially solve it, by using phonetic confusion networks, confidence estimation techniques and speech segmentation. I show that the prototype I developped yields performances comparable to state-of-the-art of more standard design

Un système de synthèse de parole par concaténation d'unités acoustiques utilise un dictionnaire de ces unités, construit à partir d'un corpus de parole mono-locuteur segmentée en éléments acoustiques, généralement phonétiques. Pour atteindre une qualité de parole synthétique suffisante, ce dictionnaire doit être richement fourni, et par conséquent nécessite un corpus de plusieurs heures de parole.La segmentation manuelle d'un tel corpus de parole est fastidieuse, d'où l'intérêt de la segmentation automatique. À condition de disposer des transcriptions phonétiques réelles des énoncés, les méthodes automatiques produisent une segmentation de qualité approximativement équivalente à celle d'une segmentation manuelle. Cependant, la transcription manuelle du contenu phonétique du corpus de parole est également fastidieuse.
Cette étude concerne la segmentation automatique de parole en phones qui utilise des transcriptions phonétiques automatiquement produites à partir du texte. Elle porte sur la détection et la correction des erreurs d'étiquetage phonétique que contiennent généralement ces transcriptions phonétiques automatiques. Les résultats obtenus dans cette étude sont significativement positifs.

Full textAbstract:
Children with slow expressive language development often catch up to their normally developing peers in expressive language, but may still exhibit difficulties with metalinguistic skills. Research shows that children who have difficulty with phonemic awareness also have difficulty with reading, which is important for success in school. Speech-language pathologists assist children who have difficulty with expressive oral language and facilitate language development in children who have difficulties with learning metalinguistic skills, such as phonemic awareness. The purpose of the present study was to compare the phoneme segmentation skills in three groups of children: (a) children with a history of oral expressive language delay (HELD) (n= 22) who were identified as toddlers with slow developing expressive language, but caught up to their normally developing peers by first grade; (b) children identified as toddlers with slow developing oral expressive language and by first grade still maintained the expressive language delays (ELD) (n= 7); and (c) children who were identified at age two as developing normal oral expressive language and maintained normal oral expressive language development (NL) (n= 23) in first grade. The children participated in a phonological segmentation test. The study answered four questions: Is there a significant difference among the three groups of children in the number of correct responses on a phonological segmentation test at ( 1 ) the one phoneme level, (2) the two phoneme level, (3) the three phoneme level, and ( 4) the total number of correct responses. Utilizing an ANOVA test, a significant difference was found among the groups at the two phoneme level, with a trend toward a significant difference at the one phoneme level. Other significant differences were not found. The difference at the two phoneme level was between the ELD group and the normal group, as well as between the ELD group and the HELD group.

Full textAbstract:
With a dramatic economic growth rate of 10% per year, China, as one of the Big Emerging Markets, has drawn increasing attention from both academia and industry. Its market potential and growth rate is believed to be the top attraction for global investment. In many sectors, the increasing number of options available to consumers has led to the emergence of a consumer society in China and has further fed the development of variance in consumer behaviour. This has imposed imperatives of consumer research in China, especially market segmentation research, on both foreign multinational companies and indigenous 5 manufacturers, in order i) to identify the unique needs of consumers, to provide more desirable product/service packages, and iii) to communicate brand value via more appropriate messages to targeted consumers.

The goal of this thesis is to develop a smartphone application for augmented reality view; it is an initial attempt to realize a driver assistance functionality using just a smartphone and an external lens. Initially it depicts a brief analysis about the most feasible development technologies for mobile application development, selecting a proper lens and positioning of the smartphone in the car. Later, it discusses the strategies for real-time object detection using OpenCV; the video frames are processed using the strategies to find patterns in the videos. Different techniques like Hough-line transform, watershed, contour detection, color segmentation, color thresholding and HAAR cascades are implemented and compared in terms of real time detection of the desired objects. Then a unified algorithm is implemented for the given scenario which overcomes the challenges faced during the conceptualization phase. Finally, the results are depicted with the snapshots of the real time detection done from the smartphone and then evaluated against the vision of the application and the achieved tasks. This thesis is concluded by stating the prospects of this mobile application in the future.

Full textAbstract:
This study investigated the effects of individualized writing instruction with and without phonemic segmentation on the standard spelling performance of at-risk first graders. Forty-two students from fifteen non-public elementary school Chapter I programs participated in the study.
Subjects were pretested using the Yopp-Singer Test of Phoneme Segmentation to determine their phonemic awareness level. Students were matched in triads and placed in one of two treatment groups or the control group using a constrained random assignment procedure. The Basic Achievement Skills Individual Screener (BASIS) spelling subtest was administered to assess standard spelling performance.
The first treatment group received individualized writing instruction using a phonemic segmentation procedure based on the work of D. B. Elkonin and used in the Reading Recovery program for at-risk first graders. The second treatment group received individualized writing instruction where teachers supplied correct spellings. The control group received no additional writing instruction emphasizing spelling. Treatment occurred twice weekly for twelve weeks.
Following treatment students were re-evaluated using the BASIS spelling subtest and Yopp-Singer Test of Phoneme Segmentation. The Cognitive Abilities Test was also administered to determine a cognitive ability level for each subject.
Data were analyzed using a 3X3X3 analysis of covariance. Due to the impact phonemic awareness and cognitive ability have on spelling performance, the study stratified students into high, medium and low phonemic awareness levels and high, average and low cognitive ability levels. Results indicated there were no differences among the groups following treatment. As the data analysis progressed a question as to whether either treatment improved phonemic awareness arose. Analysis of variance on the mean differences of phonemic awareness scores indicated there were no significant differences among the three groups.
Study results suggested that use of the Elkonin analysis phonemic segmentation procedure in isolation may have limited benefits in improving spelling for at-risk first graders. Additionally, the study pointed to the need for further research on phonemic awareness training programs and the importance of earmarking financial resources for students who will benefit most from phonemic awareness instruction.

Online learning has altered music education remarkable in the last decade. Large and increasing amount of music performing learners participate in online music learning courses due to the easy-accessibility and boundless of time-space constraints.
Singing can be considered the most basic form of music performing. Automatic singing voice assessment, as an important task in Music Information Retrieval (MIR), aims to extract musically meaningful information and measure the quality of learners' singing voice.
Singing correctness and quality is culture-specific and its assessment requires culture-aware methodologies. Jingju (also known as Beijing opera) music is one of the representative music traditions in China and has spread to many places in the world where there are Chinese communities. Our goal is to tackle unexplored automatic singing voice pronunciation assessment problems in jingju music, to make the current eurogeneric assessment approaches more culture-aware, and in return, to develop new assessment approaches which can be generalized to other musical traditions.El aprendizaje en línea ha cambiado notablemente la educación musical en la pasada década. Una cada vez mayor cantidad de estudiantes de interpretación musical participan en cursos de aprendizaje musical en línea por su fácil accesibilidad y no estar limitada por restricciones de tiempo y espacio. Puede considerarse el canto como la forma más básica de interpretación. La evaluación automática de la voz cantada, como tarea importante en la disciplina de Recuperación de Información Musical (MIR por sus siglas en inglés) tiene como objetivo la extracción de información musicalmente significativa y la medición de la calidad de la voz cantada del estudiante. La corrección y calidad del canto son específicas a cada cultura y su evaluación requiere metodologías con especificidad cultural. La música del jingju (también conocido como ópera de Beijing) es una de las tradiciones musicales más representativas de China y se ha difundido a muchos lugares del mundo donde existen comunidades chinas.Nuestro objetivo es abordar problemas aún no explorados sobre la evaluación automática de la voz cantada en la música del jingju, hacer que las propuestas eurogenéticas actuales sobre evaluación sean más específicas culturalmente, y al mismo tiempo, desarrollar nuevas propuestas sobre evaluación que puedan ser generalizables para otras tradiciones musicales.

Full textAbstract:
In this research work, we develop an obstacle detection and emergency exit sign recognition system on a mobile phone by extending the feature from accelerated segment test detector with Harris corner filter. The first step often required for many vision based applications is the detection of objects of interest in an image. Hence, in this research work, we introduce emergency exit sign detection method using colour histogram. The hue and saturation component of an HSV colour model are processed into features to build a 2D colour histogram. We backproject a 2D colour histogram to detect emergency exit sign from a captured image as the first task required before performing emergency exit sign recognition. The result of classification shows that the 2D histogram is fast and can discriminate between objects and background with accuracy. One of the challenges confronting object recognition methods is the type of image feature to compute. In this work therefore, we present two feature detectors and descriptor methods based on the feature from accelerated segment test detector with Harris corner filter. The first method is called Upright FAST-Harris and binary detector (U-FaHB), while the second method Scale Interpolated FAST-Harris and Binary (SIFaHB). In both methods, feature points are extracted using the accelerated segment test detectors and Harris filter to return the strongest corner points as features. However, in the case of SIFaHB, the extraction of feature points is done across the image plane and along the scale-space. The modular design of these detectors allows for the integration of descriptors of any kind. Therefore, we combine these detectors with binary test descriptor like BRIEF to compute feature regions. These detectors and the combined descriptor are evaluated using different images observed under various geometric and photometric transformations and the performance is compared with other detectors and descriptors. The results obtained show that our proposed feature detector and descriptor method is fast and performs better compared with other methods like SIFT, SURF, ORB, BRISK, CenSurE. Based on the potential of U-FaHB detector and descriptor, we extended it for use in optical flow computation, which we termed the Nearest-flow method. This method has the potential of computing flow vectors for use in obstacle detection. Just like any other new methods, we evaluated the Nearest flow method using real and synthetic image sequences. We compare the performance of the Nearest-flow with other methods like the Lucas and Kanade, Farneback and SIFT-flow. The results obtained show that our Nearest-flow method is faster to compute and performs better on real scene images compared with the other methods. In the final part of this research, we demonstrate the application potential of our proposed methods by developing an obstacle detection and exit sign recognition system on a camera phone and the result obtained shows that the methods have the potential to solve this vision based object detection and recognition problem.

Full textAbstract:
Marketing and advertisement activities are transforming as new digital media streams emerge. It is believed that the first major digital transition took place when broadcast media such as television and cinema, also called first screen, to the PC Internet, referred to as the second screen, entered the media industry. The last couple of years saw an expanding transition into the third screen, which is the mobile handset, commonly known as cellphones in South Africa.
The rapid explosion of mobile phones and other mobile devices has created a new marketing channel. The use of Short Messaging Service, Multimedia Message Service, Graphic WAP Banners, and Video Clips to communicate with customers through their mobile devices / cellphones has gained popularity, making the mobile phone the ultimate medium for one–to–one or one–to–many marketing. And the more mobile handsets penetrate the mass market, the greater are the opportunities for advertising experiences.
This exploratory study investigates the impact / effectiveness of mobile advertising to consumers in the short–term insurance industry. The study briefly focuses on whether marketers are reaping the benefits of using this medium to communicate and market their products and services to the identified target market.
The findings indicate that mobile advertising has an impact on consumers in the short–term insurance industry. It was also envisaged that where mobile advertising seems to have no effect, the root of the problem lies in the mass marketing approach. Customers are looking for full customisation of mobile marketing messages, based on their individual requirements, tastes, preferences, location, time, and it should also add value to consumers. For maximum impact, it is also recommended that marketers should build measurements, targeting and optimisation into their campaign processes.Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2011.

In this work, three proposals of systems have been developed using a frontal camera to monitor the driver and enabling to identificate if a cell phone is being used while driving the vehicle. It is estimated that 80% of crashes and 65% of near collisions involved drivers who were inattentive in traffic for three seconds before the event. Five videos in real environment were generated to test the systems. The pattern recognition system (RP) uses adaptive skin segmentation, feature extraction, and machine learning to detect cell phone usage on each frame. The cell phone detection happens when, in periods of 3 seconds, 60% (threshold) of frames or more are identified as a cell phone use, individually. The average accuracy on videos achieved was 87.25% with Multilayer Perceptron (MLP), Gaussian activation function, and two neurons of the intermediate layer. The movement detection system (DM) uses optical flow, filtering the most relevant movements of the scene, and three successive frames for detecting the movements to take the phone to the ear and take it off. The DM proposal was not demonstrated as being an effective solution for detecting cell phone use, reaching an accuracy of 52.86%. The third solution is a hybrid system. It uses the RP system for classification and the DM for choosing the RP parameters. The parameters chosen for RP are the threshold and the classification system. The definition of these two parameters occurs at the end of each period, based on movement detected by the DM. Experimentally it was established that, when the movement induces to use cell phone, it is proper to use the threshold of 60%, and the classifier as MLP/Gaussian with seven neurons of the intermediate layer; otherwise, it is used threshold 85%, and MLP/Gaussian with two neurons of the intermediate layer for classification. The hybrid solution is the most robust system with average accuracy of 91.68% in real environment.
Neste trabalho, são desenvolvidas três propostas de sistemas que permitem identificar o uso de celular, durante o ato de dirigir um veículo, utilizando imagens capturadas de uma câmera posicionada em frente ao motorista. Estima-se que 80% das colisões e 65% das quase colisões envolveram motoristas que não estavam prestando a devida atenção ao trânsito por três segundos antes do evento. Cinco vídeos em ambiente real foram gerados com o intuito de testar os sistemas. A proposta de reconhecimento de padrões (RP) emprega segmentação de pele adaptativa, extração de características e aprendizado de máquina (classificador) na detecção do celular em cada quadro processado. A detecção do uso do celular ocorre quando, em períodos de 3 segundos, ao menos em 60% dos quadros (corte) são identificados com celular. A acurácia média nos vídeos alcançou 87, 25% ao utilizar Perceptron Multi-camadas (MLP) com função de ativação gaussiana e dois neurônios na camada intermediária como classificador. A proposta de detecção de movimento (DM) utiliza o fluxo ótico, filtragem dos movimentos mais relevantes da cena e três quadros consecutivos para detectar os momentos de levar o celular ao ouvido e o retirá-lo. A aplicação do DM, como solução para detectar o uso do celular, não se demostrou eficaz atingindo uma acurácia de 52, 86%. A terceira proposta, uma solução híbrida, utiliza o sistema RP como classificador e o de DM como seu parametrizador. Os parâmetros escolhidos para o sistema de RP são o corte e o sistema classificador. A definição desses dois parâmetros ocorre ao final de cada período, baseada na movimentação detectada pela DM. Com experimentações definiu-se que, caso a movimentação induza ao uso do celular, é adequado o uso do corte de 60% e o classificador MLP/Gaussiana com sete neurônios na camada intermediária, caso contrário, utiliza-se o corte de 85% e classificador MLP/Gaussiana com dois neurônios na mesma camada. A versão híbrida é a solução desenvolvida mais robusta, atingindo a melhor acurácia média de 91, 68% em ambiente real.

Full textAbstract:
La dysarthrie est un trouble de la parole affectant la réalisation motrice de la parole causée par des lésions du système nerveux central ou périphérique. Elle peut être liée à différentes pathologies : la maladie de Parkinson, la Sclérose Latérale Amyotrophique(SLA), un Accident Vasculaire Cérébral (AVC), etc. Plusieurs travaux de recherche ont porté sur la caractérisation des altérations liées à chaque pathologie afin de les regrouper dans des classes de dysarthrie. La classification la plus répandue est celle établie parF. L. Darley comportant 6 classes en 1969, (complétée par deux classes supplémentaires en 2005)Actuellement, l’évaluation perceptive (à l’oreille) reste le standard utilisé dans lapratique clinique pour le diagnostique et le suivi thérapeutique des patients. Cette approcheest néanmoins reconnue comme étant subjective, non reproductible et coûteuseen temps. Ces limites la rendent inadaptée à l’évaluation de larges corpus (dans le cadred’études phonétiques par exemple) ou pour le suivi longitudinal de l’évolution des patientsdysarthriques.Face à ces limites, les professionnels expriment constamment leur besoin de méthodesobjectives d’évaluation de la parole dysarthrique. Les outils de Traitement Automatiquede la Parole (TAP) ont été rapidement considérés comme des solutions potentiellespour répondre à cette demande.Le travail présenté dans ce rapport s’inscrit dans ce cadre et étudie l’apport quepeuvent avoir ces outils dans l’évaluation de la parole dysarthrique, et plus généralementpathologique.Dans ce travail, une approche pour la détection automatique des phonèmes anormauxdans la parole dysarthrique est proposée et son comportement est analysé surdifférents corpus comportant différentes pathologies, classes dysarthriques, niveaux desévérité de la maladie et styles de parole. Contrairement à la majorité des approchesproposées dans la littérature permettant des évaluations de la qualité globale de la parole(évaluation de la sévérité, intelligibilité, etc.), l’approche proposée se focalise surle niveau phonème dans le but d’atteindre une meilleure caractérisation de la dysarthrieet de permettre un feed-back plus précis et utile pour l’utilisateur (clinicien, phonéticien,patient). L’approche s’articule autours de deux phases essentielles : (1) unepremière phase d’alignement automatique de la parole au niveau phonème (2) uneclassification de ces phonèmes en deux classes : phonèmes normaux et anormaux. L’évaluation de l’annotation réalisée par le système par rapport à une évaluationperceptive d’un expert humain considérée comme ”référence“ montre des résultats trèsencourageants et confirme la capacité de l’approche à detecter les anomalies au niveauphonème. L’approche s’est aussi révélée capable de capter l’évolution de la sévéritéde la dysarthrie suggérant une potentielle application lors du suivi longitudinal despatients ou pour la prédiction automatique de la sévérité de leur dysarthrie.Aussi, l’analyse du comportement de l’outil d’alignement automatique de la paroleface à la parole dysarthrique a révélé des comportements dépendants des pathologieset des classes dysarthriques ainsi que des différences entre les catégories phonétiques.De plus, un effet important du style de parole (parole lue et spontanée) a été constatésur les comportements de l’outil d’alignement de la parole et de l’approche de détectionautomatique d’anomalies.Finalement, les résultats d’une campagne d’évaluation de l’approche de détectiond’anomalies par un jury d’experts sont présentés et discutés permettant une mise enavant des points forts et des limites du systèmeDysarthria is a speech disorder resulting from neurological impairments of the speechmotor control. It can be caused by different pathologies (Parkinson’s disease, AmyotrophicLateral Sclerosis - ALS, etc.) and affects different levels of speech production (respiratory,laryngeal and supra-laryngeal). The majority of research work dedicated tothe study of dysarthric speech relies on perceptual analyses. The most known study, byF. L. Darley in 1969, led to the organization and the classification of dysarthria within 6classes (completed with 2 additional classes in 2005).Nowadays, perceptual evaluation is still the most used method in clinical practicefor the diagnosis and the therapeutic monitoring of patients. However, this method isknown to be subjective, non reproductive and time-consuming. These limitations makeit inadequate for the evaluation of large corpora (in case of phonetic studies) or forthe follow-up of the progression of the condition of dysarthric patients. In order toovercome these limitations, professionals have been expressing their need of objectivemethods for the evaluation of disordered speech and automatic speech processing hasbeen early seen as a potential solution.The work presented in this document falls within this framework and studies thecontributions that these tools can have in the evaluation of dysarthric, and more generallypathological speech.In this work, an automatic approach for the detection of abnormal phones in dysarthricspeech is proposed and its behavior is analyzed on different speech corpora containingdifferent pathologies, dysarthric classes, dysarthria severity levels and speechstyles (read and spontaneous speech). Unlike the majority of the automatic methodsproposed in the literature that provide a global evaluation of the speech on generalitems such as dysarthria severity, intelligibility, etc., our proposed method focuses onthe phone level aiming to achieve a better characterization of dysarthria effects and toprovide a precise and useful feedback to the potential users (clinicians, phoneticians,patients). This method consists on two essential phases : (1) an automatic phone alignmentof the speech (2) an automatic classification of the resulting phones in two classes :normal and abnormal phones.When compared to an annotation of phone anomalies provided by a human expertconsidered to be the ”gold standard“, the approach showed encouraging results andproved to be able to detect anomalies on the phone level. The approach was also able to capture the evolution of the severity of the dysarthria suggesting a potential relevanceand use in the longitudinal follow-up of dysarthric patients or for the automatic predictionof their intelligibility or the severity of their dysarthria.Also, the automatic phone alignment precision was found to be dependent on the severity,the pathology, the class of the dysarthria and the phonetic category of each phone.Furthermore, the speech style was found to have an interesting effect on the behaviorsof both automatic phone alignment and anomaly detection.Finally, the results of an evaluation campaign conducted by a jury of experts on theannotations provided by the proposed approach are presented and discussed in orderto draw a panel of the strengths and limitations of the system

The goal of this study is to evaluate the effects of training in phoneme segmentation on Taiwanese EFL first-graders’ early reading ability. Thirty students from an elementary school in Taipei City were selected to participate in the present study. Fifteen subjects were assigned to the experimental group (the phoneme segmentation group) and the other fifteen students were in the control group (the phonics group). These children had no extra English learning experiences outside the EFL classroom at the elementary school before and during the ten-week experimental span. The experimental group received training in segmenting words into phonemes, as well as training in correspondence between letter names and letter sounds. The control group received only the training in letter names and letter sounds. The experiment of the respective conditions lasted for twenty 20-minute class period over a ten-week period of time. Subjects’ development of early reading skill was measured by the tests on letter-name and letter-sound knowledge, phoneme segmentation ability and word recognition ability both in the pretest and posttest. Results indicated that after the intervention, the experimental group outperformed significantly the control group in overall early reading ability, phoneme segmentation ability and word recognition ability in the posttest. In addition, comparison of within group performance between the pretest and posttest revealed that the experimental group improved significantly in overall early reading ability, phoneme segmentation ability and word recognition ability, while the control group did not make any significant improvement on any of the three measures. However, both groups did not improve significantly in letter-name and letter-sound correspondence. The reason may be due to “ceiling effect” as shown in the pretest. The findings of this study are consistent with those in previous studies on English-speaking L1 children. It suggested that training in phoneme segmentation, combined with phonics instruction, can significantly better help improve Taiwanese EFL children’s emergent literacy in L2.

This thesis evaluates the market segmentation of mobile phones in Taiwan based on customers’ perspectives. This thesis’s findings suggest that mobile phones function can be divided into six service factors, namely, news report service as the most important followed by transaction service, entertainment service, personal service, internet and multimedia services, and financial and security service. Five market segments were identified based on these six service factors. Results indicated that six service factors were significantly different among the five segments. In addition, the characteristics of these five market segments were discussed in this study.

Ever since the authority in Taiwan has release the telecommunicationsrules, the cellular phones are prevalent increasingly. For standing seizedof the market, each manufacturer has developed new product to attract consumers actively. However, no one can satisfy all consumers havingdifferent needs, so the purpose of the research wish to segment the market,and applies empirical in real world. We chose "physical attributes of the product" variables to segment currentconsumers and potential consumers into four distinct clusters:"Basic demander"、"Product-oriented consumer"、"Epicurean"、"Efficiency seeker". The characyeristic that members within the cluster arerelatively homogeneous and members in different clusters are relativelyheterogeneous was empirically testified by this research. Besides, we selected for variables "lift-style"、"store feature"、"informational source"、"demographic" and "potential market evaluation" to describe these four segments. The conclusions of this research, we can find that "Epicurean" is more enamored of buying famous brands than other clusters. "Basic demander" requests cellular phones that only have the same functions of the generictelephones, and "Efficiency seeker" makes a feature of service.

The primary purpose of this study was to compare performance on phonemic
awareness tasks while controlling for variables including the linguistic complexity of
word and nonword stimuli, and administration and scoring procedures. Twenty-five
kindergarten and 25 grade one students were administered five phonemic awareness tasks
including four different phoneme segmentation tasks and a blending task, a vocabulary
test, and real word identification and nonword decoding tasks. The relationship among
the phonemic awareness tasks was analyzed through intercorrelations, factor analyses,
and examination of relative degree of difficulty. There was a high degree of convergence
among tasks, particularly those with similar task demands. The relationship between
performance on phonemic awareness tasks and real word and nonword reading tasks was
also compared. In most cases, students who were able to decode nonwords also
performed well on the phonemic awareness tasks. A multiple regression revealed that the
best predictor of nonword decoding was an oral phonemic segmentation task. Theoretical
and practical implications of these findings were discussed.

Phone segmentation involves partitioning a continuous speech signal into discrete phone units. It is often required in some areas of speech processing, such as acoustic-phonetic analysis, speech recognition, speaker recognition, speech synthesis, and annotations of speech corpus. Manual phone segmentation is time consuming, and its result may be inconsistent because of the subjective criteria of different transcribers. Therefore a method of automatic phone segmentation is desirable. A typical approach is to align the speech signal to its phone transcripts in an utterance. The forced alignment based on hidden Markov model is a way to locate phone boundaries when the phone transcripts of the target utterance are available. This supervised method usually obtains high accuracy. However, the training speech signal and their transcripts are unavailable in some applications. Hence, unsupervised methods are used. If there is no linguistic knowledge (such as, orthographic or phonetic transcripts) of given speech data, phone segmentation is performed in blind method. However, this approach is difficult to obtain a high accuracy. Obtaining a high level of accuracy by using the blind method is challenging. This dissertation addresses the problem of blind phone segmentation. The band energies of speech signals are calculated for feature extraction. Four methods for blind phone segmentation are proposed. They are based on (1)Delta spectral function, (2)Band-energy tracing technique, (3)Gaussian function, and (4)Legendre polynomial approximation. English speech corpus, TIMIT, was examined. Experimental results showed that the proposed methods were more accurate than previous methods. For the method using BE tracing technique, Chinese speech corpus, TCC300, was also evaluated to reveal the language-independent problems. Noise influences were investigated in the methods using Gaussian function and Legendre polynomial approximation.

This study aimed to investigate the effects of phonemic segmentation instruction on Taiwanese first graders’ decoding and examine the development of their phonemic segmentation ability. The study was conducted in an elementary school in Taipei County. Sixty out of 369 students were selected and divided equally into the experimental and control groups in the study. Both groups received parallel treatment for 18 weeks. The experimental group received phonemic segmentation instruction while the control group was taught to decode words in traditional manner. Data of the study were collected from multiple sources: the DIBELS LNF (Letter Naming Fluency) test, the DIBELS PSF (Phoneme Segmentation Fluency) test, researcher-designed decoding tests, questionnaires and semi-structured interviews. Results revealed that (1) the experimental group improved significantly, whereas the control group showed non-significant improvement in the post PSF test. (2) Both the experimental and control groups improved significantly in the post decoding tests, but the experimental group performed significantly better. (3) Students of the experimental group employed the partial phonemic segmentation skill to decode words. (4) They were fond of phonemic segmentation skill instruction and felt they were able to segment the taught phonemes. They also stated that phonemic segmentation is easier than phoneme blending, which is different from what has been claimed about the difficulty level of phonemic awareness tasks.

This paper proposes a text-independent sequential phone boundary detection algorithm. Without any previous knowledge, an automatic phone segmentation system can be constructed. The method is to search for a candidate phone boundary and then follow by a verification process. The phone segmentation is accomplished when the phone boundaries are verified. The wavelet parameters are calculated in a frame of variable frame length for searching for the candidate phone boundaries. The Bayesian information criterion corrected (BICC) and normalized spectral variation function (SVF) are applied for verifying the phone boundaries. To evaluate this proposed algorithm, the experiment was conducted on TIMIT corpus. The performance of phone segmentation was measured in F-value. In the condition of 20-ms tolerance, the average F-value of 640 test utterances is 72%. Among them, 422utterances get the F-value larger than 70%.

Segmentation is the preprocessing work in a speech recognition system.In segmentation,using phoneme as basic unit can reduce the size of memory and the amount of mathematical calculation. Upon this, in this paper, we use phoneme as the basic unit to deal with the segmentation and recognition of speech in speaker- depen- dent and various phonetic environments. Considering the various phonemic environments, the experimental samples of segmention are made of two connected meaningless words to identify the effecti- veness of the segmental method in this paper used. After that, we use the continous sentence as experimental samples to proceed the recognition process. In segmention, there are five feature parameters. Three of them are of frequency domain obtained by the Unbiased Log Spectral Estimation method.Another two are the d.c. offset values and the zero crossing rate of the speech signals. We also label and classify the segmented phonemes. In recognition, we use the first 15 orders of Unbiased Log Mel Scale Cepstrum as parameters to do the matching work which is to find the least distance between test and reference templates. For promoting recognition rate, we also increase the amount of reference templates in considering the interaction of two connected pnonemics . The result shows that the segmental method is highly effective with 93.4 % correct rate. And there are still a lot of works to do in recognition for the correct rate only 36.8 % .

As technology advanced, cellular phone has become more and more popular, in order to attract consumers while marching into the third generation wireless communicating system, telecommunication operators have to find out what are the product attributes consumers are looking for and select one of the most profitable segmentation to develop effective marketing strategy. To achieve these objectives, the study was investigated by questionnaire survey and extracted five factors from benefit variables by factor analysis. In addition, by applying clustering analysis three consumer groups were segmented. The study then further analyzed consumer’s characteristic according to significant variables of demographic variables, and purchase decision-making variables. The study has reached five conclusions. First, quality of communication is most important to consumer; second, the demographics variables of age and income in each segment are significantly different; third the purchase decision-making variables of consume volume and communicating rate are significantly different; fourth, lack of cellular phone product is the main reason consumers are refusing to use 3G services; fifth, free calling in same network is the most attracting reason.

By improved manufacturing skill, mobile phone has become more easily to use and carry. Besides, the decreasing rate of mobile phone and communication service makes mobile phone more and more popular. In order to attract consumers and provide diversified multi-media service by 3rd generation wireless communicating system, mobile phone communication service providers have to find out the important communicating service and improve their service quality by knowing their customer satisfaction. Customer satisfaction could also provide message for service providers to select one of the most benefit segmentation, and develop effective marketing strategy. To achieve these objectives, the study was investigated by questionnaire survey with stratified random sampling and extracted six factors from benefit variables by factor analysis. In addition, four consumer groups were separated out by clustering analysis. Furthermore, the study analyzed consumer’s characteristic according to significant variables of demographic variables, geographic variables, and purchase decision making variables. Lastly, evaluated customer satisfaction of each service providers by attribute rating map mentioned by Marr in1986. The results show: 1. The demographics variables: gender; age and occupation in each segment are significantly different. 2. The geographic variables: residency in each segment is significantly different. 3. The purchase decision making variables: communicating rate and communicating frequency are significantly different.

Due to the fast-developed technology and rapid economic growth in recent years, a highly consumer society is developed and students have higher consuming ability gradually. Some products are very popular among students. For example, PC, mobile phone, scooter, video game and other electronic product. It seems the trends of design and appearance are getting younger and more delicate. The main purpose is to occupy the market of college students. The marketing staffs do rack their brains to conceive manifold marketing activity facing the numerous homogeneous products and severe competitive market. The purpose of this thesis is to explore the possible attitude of college students of different life style segmentation when they purchase mobile phone based on the point of view of consumers. The attitude aspects include purchasing intention, how the lifestyle influences purchasing behavior and the preference differences of mobile phone function demand. Hoping the result of the thesis provide advantageous information for mobile phone manufactures during marketing strategy implement period. The study adopts Howard-Sheth model as the conceptual framework. With AIO lifestyle variables as market segmentation base, the study uses product attribute, population statistics, attitude and purchasing intention as variables. We use consumption reality variable to describe consumer behavior and attempt to examine the degree of difference significance. The thesis is focus on the mobile phone with telecommunication function. The study object is college students in HsinChu area. The sampling survey was taken during Oct. to Dec. in 2007. According to the study result, college students purchased mobile phone in HsinChu area can treat lifestyle as useful segmentation variables to divide into three types of “subjective”, “pinch pennies” and “pragmatic.” Except the age of population statistics and consumption reality, mobile phone consumers of each segmentation in gender of population statistics, institute, monthly disposable income, and product attribute evaluation criteria, product attitude evaluation criteria and purchasing intention evaluation criteria have significant differences.

The importance of relevant research on mobile products increases as the rapid development and keen competition of the mobile phone business. The comprehensiveness and operational convenience of the interface design are then the most concern. Speaking of the icon design as the interface between mobile phone and users, appropriate metaphor shall be taken into consideration. Icons, a kind of graphical metaphor, should be designed to let users quickly catch the exact ideas of what the icons are for. Thus, the iconic metaphor shall be carefully selected to visually represent the targeted functions which in turn, could enhance the user’s comprehensive levels. The iconic metaphor plays a vital role in icon design. The primary research purposes were to investigate the needs of end users with various technological sensitivities on main menu functions of mobile phones, as well as the appropriate iconic metaphors. The card sorting and co-discovery methods were adopted to collect users’ data. Accordingly, the requirements and mental models of highly or medium technological sensitive users toward the main menu of mobile phones were generated. Also, what types of iconic metaphor might be accepted by end users were discussed too. The result showed that a total of 13 items were needed on the main menu of a mobile phone for the highly technological sensitive users, while the medium technological sensitive users required 10 items only. The study discovered that highly technological sensitive users viewed a mobile phone like a 3C or multimedia device. They demanded that the main menu of a mobile phone shall be charily categorized and the secondary menus shall be organized hierarchically according functional characteristics. The acceptable metaphors for this user group tends to be multifunctional, technology-oriented and active controlled. As for the medium technological sensitive users, the main concern of using mobile phones is to communicate and to deal with personal affairs. Their mental models seem to prefer the icons with simplicity features. As a result, the acceptable metaphors of this user group incline to be simple functioned, traditional life style and less active controlled, which were categorized as the hierarchical and function-oriented types of metaphors. Finally, concrete objects were used by them to visually represent icons.

The objective of this study is to explore the types of the cellular phone consumers and their perceptions and preferences on telecommunication companies. Seven factors are extracted from lifestyle variables as the bases of segmentation. These factors are “fashion”, ”information seeking”, ”independence”, ”fast tempo of life”, ”conspicuous”, ”outgoing” and ”busy”. Using cluster analysis and discriminant analysis, cellular phone users can be divided into three segments -“the Follower”, “the Conservative” and “the Fashion Leader”. In addition, the differences of the perceptions to the positions of telecom companies and the differences of the preferences of telecom companies between different segments are analyzed by multidimensional scaling technique (MDS). To all three segments, FarEastone Telecommunications Co., Ltd. and Pacific Cellular Corp. (PCC) are most similar companies; ChungHwa Telecommunication Co., Ltd. and TransAsia Tele-communications are most dissimilar ones. All three segments take “receivability”, “tariff” and “service” as the three most important attributes and “value-added features” as the most unimportant one in choosing a telecom company. But the rankings of the importance of other attributes between three segments are different. The Follower’s preference ranking of telecom companies is PCC, FarEastone, ChungHwa, TransAsia, KG Telecom (KGT) and Mobitai Communications. The gap between PCC and FarEastone is very small. The Conservative’s preference ranking is the same. But the gap between TransAsia and KGT is small, too. For the Fashion Leader, the preference ranking is FarEastone, PCC, ChungHwa, KGT, Mobitai and TransAsia. Finally, all three segments’ perceptions on the degree of telecom companies’ internationalization did not match the real situation and they don’t care about that. Therefore, the internationalization of a telecom company is not suitable to be a marketing appeal.

The deregulation of telecommunication industry in 1997 urged the competition especially in the mobile phone service market. The penetration rate of mobile phones in Taiwan was 112% on June in 2003. The highest rate in the world means that the market for mobile phones was saturated. The main goal of operators is to maintain the long term relationship with the customers. The operators intend to further understand subscribers’ characteristics and use market segmentation to satisfy different demands. Moreover, many countries have intiated the phone number portability policy which makes subscribers have apparent volition to switch the original opeator. When Taiwan applies this policy in 2005, there will be more switching users. The operators will try every effort to prevent that from happening and focus their marketing strategies on them. There is no similar research in Taiwan about how the carrying numbers affect the switching users. This study established a database and conducted cluster analysis with statistical methods and artificial neural networks as our tools of data mining. The results clearly indicate sensible market segmentation and the assessments between clusters were made. All of these information will help us better understand the characteristics of switching users. The operators may take advantages of these findings to enhance the customers’ relationship.

Taiwan’s telecommunication market has aggregated multiple information services, and it changed the industrial and social structure. Under the pressure of NCC, every telecom vendor decreased its call charged rate. However, since the mobile-internet service was the main business of telecom vendors, they increased the penetration rate of smart phones and earned more from users of mobile internet. Besides, mobile value-added service provides more content like music, videos, online-bookstores and stock information, so it increases the total revenue of telecom vendors. Therefore, it is important for telecom vendors to provide a variety of services and to attract more customers. This study investigates the purchase behavior of the mobile telephone subscribers and divides the whole mobile telephone market properly into several segments. The characteristics and behavior of the consumers in each segment are analyzed and described to help the telecom vendors choose their adequate marketing strategies.For this purpose, EKB model is used as a conceptual frame and consumers lifestyle variables are used as basis of market segmentation. The results show: 1. the purchase motivations of the buyers in each market segment are not significantly different. 2. The demographic variables in each segment are significantly different except for gender, degree of education and place of growth. 3. The purchase decision variables: Information gathering and consumption reality in NCTU are significantly different. As a whole, the major motivation for a customer to subscribe the mobile phone service is from the introduction of friends and relatives. Quality, service and price are the major concerns in selecting telecom vendors. The top three telecom vendors are Chung-Hwa Telecom Co., Ltd., Pacific Cellular Corp, and Far-Eastone Telecommunications Corp. The telecom vendor is selected based on the price and inner-network free calling incentive. NT$2000 to NT$5000 is most acceptable for handset price to consumers with monthly bills around NT$1200 to NT$1500 after purchasing. Lastly, customers who surf on internet by their cell phones mainly spend less than an hour per day.

The two fast developing industries, mobile communication and the internet, will converge in the 21st century. It is already a reality that user is able to surf the internet or view their emails and messages directly through their mobile devices, and the 3G mobile phone will soon fulfill the dream of "Internet in the pocket". The purpose of this paper, while using Roger''s Innovation Adoption Theory as its frame, is to identify the acceptance of the 3G mobile phone based on consumers'' preference and their demand for broad band. In addition, we try to find out whether the mobile phone consumers can be segregated by their life style so as to identify target consumer groups and to provide our research results to the industry to formulate their marketing strategies. The samples we used for this study are the attendants of the 2000 Taipei Communication Exhibits. From the samples we discovered that potential users can be effectively segregated by life style and Group 2 and 4 have the highest acceptance rate, though difference do exist in terms of marketing, servicing, brand, appearance and expendability. In order to target these potential customers, different marketing strategies are required. About 70% of the sample attendants who has heard of 3G mobile phone have expressed that the new generation mobile phone can provide multifunctional services when compared to WAP and GPRS phones. Primary sources of such 3G mobile phone information comes from TV, newspapers and magazines, the rest are from internet and telecommunication industry. Majority of the sample attendants showed strong interests in this new generation mobile phone and have expressed their intention to purchase the phone within a 6 to 12 month period. Between those who accept the 3G mobile phone and those who don''t, there is a clear variance on the convenience, the expandability and the appearance.

The aim of this diploma thesis is to closely investigate and describe selected phonetic properties of Czech oral plosives [p t ť k b d ď g] in normal speech. The re- search focuses mostly on temporal characteristics in various contexts; moreover, we deal with the possible manners of plosive articulation in Czech, including non-canonical realizations. Another important part of the present study is a comparison with earlier studies. In the domain of temporal characteristics we examine the influence of various contexts on phone duration. The contexts include: phonetic context, speaker gender, the position of the plosive in the stress unit or articulation rate. We also examine a possible connection between the duration of the plosive and its realization. In the part that deals with the manner of articulation we focus on the individual phonetic properties, for which we investigate especially the conditions and degree of their stability. Furthermore we describe the specific plosive articulations in certain pho- netic contexts and some alternative realizations of certain plosives. The speech material used is mostly spontaneous. All the speakers are non- professionals from various TV broadcasts. Keywords: plosives, duration, phone segmentation, phonetic properties, pho- netic context, gender, articulation...
