Nguyen-Trong, Noe͏̈l. "L'identification des voyelles dans un espace de contrôle." Aix-Marseille 1, 1990. http://www.theses.fr/1990AIX10025.
Full textIn this work, we try to define a function through which one could "mechanically" reproduce the association between a vowel and a phoneme. The neural net of j. A. Anderson (1977) is used to classify a set of vowel spectra in order to examine the hypothesis according to which a distinctive feature can be considered as the eigenvector of a covariance matrix. A perception test shows that the dimensions of maximal variance in a vowel system, do not necessarily provide the most important part of the "information" , as it is usually admitted. We suggest that the identification of a vowel can be modelled by a dynamical system reaching a equilibrium point in a state space, in a connectionist approach

Full textThis thesis deals with the rapport substance/form. We examine the common vowels of Spanish, Japanese, French and Arabic in /ptk/ context, in accented/unaccented syllabes, in steady state and in slow and fast rate. We observe the formants, Fo, duration and coarticulation. In fast rate, vowels centralize. In slow rate, compared to steady state, we observe a lot of variability amongst the languages. Formants differences between accented and unaccented are more evident in fast rate. The Fo est higher in fast rate; The Fo of the accented vowels is not always the highest. That of vowels in unaccented, median position, is generally the lowest. The duration of vowels in fast rate is short. The duration of the accented vowel is generally the longest in slow rate. That of the Japanese is highest in medium position. We observe variability in fast rate. The duration of the consonants is generally longer than that of the vowels in slow rate, it is impossible to generalize in fast rate

Full textThe derivational approach to syllables fails to express syllabic oppositions among semivowels in french and phonemic unicity of semivowels and high vowels. These segments would be better understood in terms of dynamic articulation of segmental and syllabic structure on a squeleton of temporal positions. The organisation of semivowels and high vowels on a sonorant scale and the opposition on that scale between a negative sonority and a positive one provide arguments for a minimal syllable principle. Underivability of syllable structure can be interpreted as the acoustic nature of syllables

Full textThe aim of my study is to determine the acoustic features of vowels and their auditory perception. The results of the present work are important not only for acoustic phonetics research but also for speech sunthesis and automatic recognition of the arabic speech. The paper is devided into two parts. The first one deals with acoustical analysis of 'standard'arabic vowels. The second part is about psycho-acoustical analysis of microprosodic variations. The acoustical analysis consist in the spectral analysis and normalisation of vowels, on the one hand, and on another the variations of fo, duration and intensity. The spectral analysis emphasises on differences between subjects. The results show that each individual realization has its own acoustical caracteristic (f1-f2 and f1 f2 - f2 f3). The study fo micro and macro-variations in the acoustical realization of vowels contributes to speech synthesis and the recognition of adjacent segment. In the second part of this paper, i tried to estimate the differential perception thresholds for fo, duration and intensity of vowels. By means of static synthetical stimuli, i tried to evaluate the perception of microprosodic variations which have been analysed in the first part. The differential thresholds we used to separate between perceptible and non perceptible variations. This approach allows us to determine where, when and how the specific effects of vowels effects their perception. The perceptual study of linguistic functions of fo, duration and intensity in continuous arabic speech have to be prolonged. This second part only shows how these variations in physical features can be considered significant
Thill, Tina. "Une étude acoustique et comparative sur les voyelles du luxembourgeois." Thesis, Sorbonne Paris Cité, 2017. http://www.theses.fr/2017USPCA078/document.
Full textThis thesis is part of a descriptive work in acoustic phonetics, with the aim of studying the productions of Luxembourgish vowels in native and non-native speech. Its objective is to conciliate the variation of Luxembourgish, mainly a spoken language, composed of many regional varieties, evolving in a multilingual context, and the learning of Luxembourgish as a foreign language in the Grand-Duchy of Luxembourg. As we assume the fact that language learning implies knowledge of sound contrast in speech, we investigate the productions of speakers whose mother tongues have different features than Luxembourgish, such as French, to see whether if the contrast are reproduced in non-native speech. Productions of French speakers are compared to those of native speakers from the region around the capital city of the Grand-Duchy of Luxembourg, whose variety serves as a reference to the teaching of Luxembourgish as a foreign language. The purpose of the study is the following :- to extend the descriptions on the acoustic properties of vowels produced in a regional variety of the Grand-Duchy of Luxembourg,- to highlight the specific difficulties of productions by French learners of Luxembourgish,- to interpret the results regarding the teaching of Luxembourgish as a foreign language.Fieldwork and the creation of a corpus through recordings of 10 Luxembourg speakers and 10 French speakers are an important part of the empirical work. We obtained a corpus of 12 hours and a half of spoken and spontaneous speech, including native speech and not native of Luxembourgish and also native speech of French. This corpus represents a first corpus containing native and non-native speech of Luxembourgish and enables to conduct different comparative studies. In our thesis, we did comparative analyses of the data in read speech. The methodology we used made it possible to compare data of native and non-native speech and also data of the L1 and L2 of French speakers.The results gave information about native and non-native productions of vowels. They showed that, on the one hand, vowel productions vary among speakers, even if these speak the same regional variety and, on the other hand, French speakers who learn Luxembourgish at B1/B2 level have difficulties producing contrasts in Luxembourgish. This concerns :- the quantity of the long vowels [i:], [e:], [a:], [o:], [u:] and short vowels [i], [e], [ɑ], [ɔ], [u],- the quality of the long vowel [a:] and the two short vowels [æ] et [ɑ],- the quality of the beginning of the diphthongs [æi], [æu], [ɑi], [ɑu].These results as well as thorough descriptions of the vowels in native speech, extend knowledge not only of Luxembourgish, but also of the variety which serves as the reference for Luxembourgish as a foreign language. In addition, they open up prospects for studying Luxembourgish by problematizing the introduction of rules for this type of education, despite the absence of language instruction in schools and the evolution of regional varieties in a concentrated geographical area

Full textThis dissertation has a double objective. On the one hand, we try to understand the impact static and dynamic cues have on the perception of Arabic vowels, and on the other hand, to evaluate the role of vowel density on the vocalic space organisation in Moroccan Arabic, Jordanian Arabic and French. First, we evaluate the role of different cues for vowel discrimination in production and perception (obtained in different consonantal environments and production situations). Results in production show that the use of dynamic cues helps to discriminate the vowels between and within the three languages. Inter-language differences may be related to the Adapted Vowel Dispersion Theory, where the vowel space in Moroccan Arabic seems more centralised than that of Jordanian Arabic or French. At the perceptual level, results indicate that vowel identification in Arabic improves when dynamic cues are used in comparison with French. Some important differences between the vowel spaces in the three languages are shown. These may be caused by vowel density effects. Although the use of dynamic cues is more adapted to Arabic, French listeners were helped when dynamic cues were available. These results indicate that static and dynamic cues are complementary in vowel description between the languages. As suggested by the Dynamic Specification model, it seems that the role of dynamic cues in vowel perception is independent from the language under scrutiny
Mastrodonato, Pantaleo. "Description phonologique du vocalisme latin à l'époque de Cicéron." Montpellier 3, 1986. http://www.theses.fr/1986MON30044.
Full textWe propose a definition of the vocalic system of latin of cicero on the basis of paradigm. Thanks to this procedure called commutation in different oppositions, we could verify the reality of the phoneme of latin vowels. After accentuation, we would also study the different vowels: grouping the most important facts in big categories (long syllables, short syllables, diphtong, nasal syllables) and then constitu tes the under categories (appearance conditions after accent, the related consonnants, neutralization etc. ). We then make a list of intra-family oppositions within phonemes (correlation), the list of distinctive traits, the classification of distinctive traits and those of phonemes. Lastly, one examines the vocalic system of the spoken language in the roman empire wich differsgreatly from the written language: this variation constitutes an important theme. Our goal therefore, is to precisely identify the structure of these vocalic phonemes, other than, from the knowledge of traditional grammar

Full textWe present an acoustic description of nasal vowels (NV) in Quebec French (QF) and Brazilian Portuguese (BP), languages that possess phonological NV in their inventories. We show that QF and BP NV have different vowel qualities: QF NV are more dispersed than BP’s, smaller contrast (for corresponding NV), and greater amplitude of formantic movement. We also assess discrimination and identification abilities of BP speakers for QF NV. We show that [œ̃] is difficult to perceive because it has no equivalent in Portuguese; variability of [ẽ]’s quality and its important dispersion makes it difficult to discriminate, while its formant movement contributes to its correct identification; [ã] and [ɔ̃] are more easily discriminated, but [ã] is misidentified in a greater proportion because it overlaps several categories, while [ɔ̃] is more easily identified because of its similarities with BP’s [õ].

Full textOur research deals with an aerodynamic, fiberscopic, acoustic and perceptive study of the nasal vowels of French. The aerodynamic data show that the carryover of the nasal airflow (NAF) is more important than the anticipation. In spontaneous speech, we find less delay than in read speech. With the fiberscopic results, we confirm that the movements of the velum start before the onset of the vowel. In spontaneous speech, we found few items with a complete closure of velum before the offset of the vowel. The aerodynamic data together with the fiberscopic data show that there is no timing between the opening of the velopharyngeal port and the beginning of NAF. The acoustic data show a correlation between the acoustic signal and the beginning of NAF for two vowels ([E~] and [A~]). We do not find a correlation between the beginning of velar movements and the acoustic signal. The results of perception tests suggest that NAF is not the primordial feature to discriminate the nasal vowel

Full textThe subject of this study is the vocalic system of french on the contrastive phonetics level with a pedagogic object. Two languages are confronted : the language of the student (the sudanese arabic "standardized") and the language that the student wants to study thoroughly (the french called "standard"). The difficulties in the acquisition of the target language are studied with comparisons (arabic and french) and the comparisons between the production of the students and the production of the french speakers (our models). The difficulties in the acquisition of a foreign language are often due to the interference of the mother language (sudanese arabic), the acquired habits in the articulation of the sudanese student are : the point of articulation (front back), the position of the lips (non-rounded and rounded), the system of aperture (limited to three degrees) and the habits, with which he must be faced, are : nasals and the system of aperture (four degrees). An acoustic analysis and tests of perception prove that there are two sorts of mispronunciation : - the mistakes which result in the incomprehension of the message - the mistakes which are just embarrassing and do not really affect the meaning of message

Full textThe analysis in parallel of speech and nasal signals permits to measure the durations of nasal coarticulation between nasal and oral segments. Specifically, aerodynamic constraints generated by the production of stop consonants delay the nasalization (velum opening) at the beginning of subsequent nasal vowels. The acoustic examination of this oral part of the nasal vowels reveals the articulatory underlying target to each nasal vowel; a fact confirmed by identification tests. These results suggest that the phonetic symbols used to represent the three French nasal vowels do not correspond to their actual articulation any more. Furthermore, the nasal coarticulation in oral vowels followed by nasal consonants indicates a tight relation between the velum opening correlated to the nasalization duration and the two articulatory dimensions of the tongue (high/low and front/back positions)

Full textThis work of moroccan arabic of rabat was divided into two main parts. In part one, an acoustic study of vowels was realized, in part two was presented the perceptual tolerance of the listener by describing vowel identification tests. The results of the spectral analysis demonstrate significant differencies in formant values, particularly between males and females when producing vowels. This can be explained by the length of the vocal tract wich is approximally inversely proportional to the formant frequency values and by the effect of consonantal context on formant frequencies. In the perceptive study, two tests were elaboreted, one with the vowel identification insert in the words and the other with the same vowels extracted out of the consonantal context. Then, the vowels spoken in syllables are identified more accurately than vowels spoken in isolation. This is co nsistent with the hypothesis that dynamic acoustic information due to the coarticulation in syllables is important for vowel identification

The analysis of vowels was e-fected by means of two complementary techniques of experimental phonetics : cineradiography as regards articulation, and spectography as regards acoustic. We have also studied the vocalic modifications produced by coarticulatory phenomena between vowels and consonants, classified according to the place of articulation bi-labial, alveodental, palatal velar and to the aspirated non-aspirated character of these consonants

Full textSince words are rarely produced in isolation, one of the first steps in acquiring new words is to segment them from continuous speech. Transitional probabilities (Saffran et al., 1996) and rhythmic units (Nazzi et al., 2006) have been proposed to be crucial at segmentation onset. Segmented word forms will then have to be stored as phonetically-specified representations for future recognition. However, Nespor et al. (2003) hypothesized that consonants, more than vowels, are involved at the lexical level, proposing a consonant bias in early word processing.The first part of my dissertation investigates preterm and full-term infants' segmentation abilities to determine when they emerge and to what extent rhythmic units are involved. The second part investigates the emergence and origin of the consonant bias in recognizing segmented word forms with full-term infants. Results show that (1) both preterm and full-term 6-month-olds are able to segment speech by using syllabic units; (2) French-learning infants switch from a vowel bias at 6 months to an adult-like consonant bias in recognizing segmented word forms; (3) the consonant bias emerging between 6 and 8 months of age, it would result from the processing and learning of the acoustic/phonetic properties on the language being acquired

Full textA phonetic and perceptual ,analysis was conducted on the six standard modern arabic vowels preceded by front, back and emphatic consonants. The analysis showed the importance of the distance between the first and the second formants (f1 and f2) in the production and perception of these vowels. This distance made it possible to categorize the vocalic space of standard arabic into two classes of vocoids: emphatic and non-emphatic. Such categorization was valitdated through a perceptual experience. Findings of this study point, then to the necessity of taking into account the distance between f1 and f2 in speechn recongnition rules for standard arabic, not exclusively the absolute values of these formants

Full textThe dissertation deals with the application of knowledge acquired from experimental phonetics to the teaching of vowels pronunciation within the framework of French as a foreign language. The formants of French and Arabic oral vowels pronounced by natives indicate that Arabic vowels /iː aː uː/ differ phonetically from French /i a u/, in particular /iː uː/, which were realized more like /e o/ of French. The acoustic study of French vowels shows that the French /u/ loses its identity when it is produced by the Jordanian learners: The formants of /u/ realized by beginners are close to those of /ø/, and close to /o/ in the realization of advanced learners. The perceptive studies confirm that the learners merge /u/ with /ø o/ and reproduce only a single sound for the following pairs: /e-ɛ/, /ø-œ/ and /o-ɔ/ whereas they realize and identify correctly /y ø/ in spite of the absence of /y ø/ in their phonological system. By contrast, the nasal vowels /ɑ̃ ɛ̃ ɔ̃/ pose a serious problem for the learners. They are mutually merged and also confused with oral vowels. The aerodynamic study of French nasal vowels, pronounced by Jordanians learners indicates that they synchronize differently the onset of nasal airflow and distribute in different manner its quantity on the vowels with regard to the realization of natives. The formants measured at the beginning of /ɑ̃ ɛ̃ ɔ̃/ show that the learners do not have the same articulatory targets for the nasal vowels as the natives. The dissertation ends up with a reflection concerning strategies of phonetic correction, materials and technical propositions for pronunciation teaching

Full textThis thesis is dedicated to the analysis of the vocalic system of the interlanguageof Moroccan students of Italian (FL). The aim of this work is to determine whichis the language that has the biggest influence on the pronunciation of Italianvowels: Arabic (NL) or French (L2).The empirical part of this research took place in the faculty of Ain Chock-Casablanca, during the academic year 2012-2013. The informants, on whose datathe research is based, were been recorded while reading a list of sentences whichcontains minimal pairs. In order to verify the correct pronunciation we used acontrol group of Italian natives (recorded at the University of Turin). All the oraldata were treated with PRAAT and analyzed in an electronic document (LFSAG).For visualization of the vowel spaces we opted for the measurement of the firstand the second formants and their display in F1-F2 diagrams.After analyzing the different errors of pronunciation of the Italian vowels wenoticed that they are attributable to phonological difficulties due to vocalicexchange of the phonemes /e/ with /i/ and /o/ with /u/ and vice-versa. Additionallythe results show that the interference of the French language less than expected,and only occurs when there are two words with the same graphical aspect. Arabic,on the other hand, as the mother tongue of all the informants, is the languagewhich has the most effect on the pronunciation Italian vowels.The analysis of the phonological system of both Moroccan and standard Arabichas revealed that it is characterized by secondary articulation manners which aretraditionally attributed to emphasis, which modifies the timbre of the consonant.The consonant in its turn change that of the adjacent vowel. While the articulationof the Italian vowels is more independent from the consonantal context, thearticulation of the Arabic vowels appears to be dependent on the context sincetheir timbre depends partially on the preceding and following consonants: if theseare emphatic, then the vowel is emphatic ([e], [o]), and if they are not emphatic,then the vowel is non emphatic ([i], [u]).The results obtained in this research confirm that what affects the pronunciation ofthe vowels are the emphatic modes present in Moroccan and standard Arabic.These difficulties can be overcome with specific exercises, which allow thestudents to acquire new articulatory habits in order to reach a good pronunciationof the Italian language
La presente tesi è dedicata all’analisi del sistema vocalico dell’interlingua deglistudenti marocchini di italiano (LS) per risalire alla lingua che interferisce di piùsulla corretta pronuncia delle vocali italiane: arabo (LM) o francese (L2).La parte empirica si è svolta presso la Facoltà di Ain Chock-Casablanca (FLSU),durante l’anno scolastico 2012-2013. Gli informanti, sui cui dati si basa la ricerca,sono stati registrati mentre leggevano una lista di frasi contenenti coppie minime.Per verificare la loro pronuncia ci siamo affidati a un gruppo di controllo nativo diitaliano (registrato presso l’Università di Torino). Tutti i dati orali sono statitrattati in una seconda fase con PRAAT e analizzati in un foglio elettronicopredisposto per la rappresentazione dei grafici (LFSAG). Per la visualizzazionedelle vocali abbiamo optato per la misura della prima e della seconda formante ela rappresentazione sui classici diagrammi F1 - F2.Dopo aver analizzato i diversi errori di pronuncia delle vocali italiane abbiamonotato che sono prevalentemente riconducibili a difficoltà fonologiche dovute alloscambio vocalico del fonema /e/ col fonema /i/ e del fonema /o/ col fonema /u/ eviceversa. I risultati ottenuti rivelano che l’interferenza della lingua francese èminore del previsto e si verifica quando si hanno due parole che presentano lostesso aspetto grafico. Quanto all’arabo è la lingua che influisce molto di più sullapronuncia delle vocali italiane essendo la madrelingua di tutti gli informanti.In effetti, l’analisi del sistema fonologico sia dell’arabo marocchino sia di quellostandard, rivela che si caratterizza per la presenza di modalità articolatoriesecondarie, ricondotte tradizionalmente alla cosiddetta enfasi che cambia il timbrodella consonate che a sua volta cambia quello della vocale adiacente. Sel’articolazione delle vocali italiane risulta più indipendente dal contestoconsonantico, quella delle vocali arabe, invece, avviene in modo dipendente dalcontesto dato che il loro timbro dipende in parte dalla consonante che precede osegue, cioè se è enfatica ne consegue una vocale enfatica ([e], [o]), e se invecenon è enfatica ne consegue una vocale non enfatica ([i], [u]).I risultati ottenuti in questa ricerca confermano che ciò che influisce sullapronuncia delle vocali italiane sono le modalità enfatiche presenti sia in dialettomarocchino sia in lingua araba. Tali difficoltà possono essere superate con degliesercizi specifici permettendo agli studenti di acquisire nuove abitudiniarticolatorie cui consegue una buona pronuncia della lingua italiana

Full textBesides my own hypothesis (chapter 1), i go through the main possibilities explaining changes - the purely linguistic ones, and the extra-linguistic ones (chapter 2). I claim that change could be observed within synchronic studies, and particularly i stress upon the variability concept (chapter 3), then i relate different theories about change's diffusion through linguistic community (chapter 4). These theoretical considerations end with the matter of change's diffusion across lexicon - neogrammarian theory versus lexical diffusion theory (chapter 5). In chapters 6 to 10, i set out four experiments about the change itself (the "what" and the "how"). First experiment, as a preliminary, lay evidence on backing from readings of parisian people (chapter 6). The second one is a large spelling survey upon pupils and students. It shows that the change appears in writing too - as spelling errors - essentially among pupils, but also among adults in special words (chapter 7). I had to define experiments to highlight changes below the conscious level of speakers. The third experiment (chapter 8) is a survey upon a small and geographically homogeneous population. It reveals differences of perception and production of vowels o and o between two generations. Chapter 9 is an analysis of categories' perception of synthetic stimuli by some thirty subjects. Chapter 10 is an acoustic analysis of these vowels out of readings and interviews of few of these subjects

Full textThis thesis concerns the comparison of the phenomena of nasal coarticulation of vowels in two languages that have phonological nasal vowels (French and Urdu) and three languages that don’t have phonological nasal vowels (American English, Bosnian and Norwegian). To evaluate the degree of nasality, we used a piezoelectric accelerometer (PA) (non invasive and transportable). Five native speakers of each language recorded the corpus of logatomes CVNC, words and sentences. This thesis shows that : (1) an inter-language difference exists with respect to nasal coarticulation strategies, confirming an already known fact, (2) the existence or absence of a phonological contrast between nasal vowels and oral vowels in a language does not necessarily have a predictable influence on the propagation of nasality, confirming an already known fact, (3) one model of anticipation of nasality may be more suitable for one language, while for another language another model may be more suitable. (4) the french auditors don’t disinguish between several degrees of contextual nasalization but there is a correlation between the quantity of vibration from the AP and the perception of the degree of nasality for the auditors of urdu. The interest of this study is that the comparison of the nasal coarticulation phenomena of vowels in the five languages was made with the same instrumentations under the same conditions. Another interest is to show the interest of the chosen method

Full textThis research focuses on a phonetic aspect that falls into three areas, phonetics, dialectology and Arabic sociophonetics. Our approach, tools and analysis are phonetic in nature. We analyzed the frequency of the first three formants [F1, F2, F3] of short cardinal vowels / i, u, a /of the Libyan Arabic of Tripoli (ALT) and we alternated the phonetic context of pharyngealized consonants / t ˁ, s ˁ , ˁ d / versus non pharyngealized / t, s, d / to verify the impact of the latter on the central frequency of formants. However, the results obtained have allowed us to compare the ALT to other popular varieties in modern Arabic. As they allowed us to make fundamental social distinctions, such as the gender. Our research problem deals with the issue of the realization of the acoustic space of vowels in ALT, in contrast with the consonant pharyngealization, the resulting co-articulatory patterns as well as the tool of 'locus equation' to reveal, all of this in a dimension of social stratification by gender. Three hypotheses were presented; the first was on the variation of the vowel space and its motivations, the second was on the appropriateness of using the locus equation and the third was related to gender distinctions. Our results, based on the analysis of a corpus of trisyllabic words [C1V1 C2V2-C3V3-] where C is either a pharyngalized consonant / s ˁ, ˁ t, d ˁ / or a non- pharyngalized consonant / s, t, d /, V is one of the three cardinal short vowels / i, u, a /, read by ten speakers (6 males and 5 females) to validate our three hypotheses. Changes in formant values of vowels, the acoustic space and the distance between the first two formants were based on three factors: 1) the consonantal context (pharyngalized vs. non- pharyngalized), 2) the prosodic position (stressed vs. unstressed), and 3) social distinction (male vs. female). Our study has been able to respond positively to the objectives assigned to it at the start: 1) on the phonetic level, it gives an overview of the vowel system of ALT and its variation with the pharyngealization 2) on the dialectological level, it answers questions from Arabic dialect typology and classification of the Eastern Libyan Arabic dialect vs Maghreb dialect and 3) on the sociophonetic level, it verifies the profound social distinction, woman's speech vs man's speech

Full textIn this thesis, we studied the perception and production of the French oral vowels by sixteen Tunisian children (8-9 years old) learning French. Data are collected at three different periods: at the beginning of their first year of learning, after nine months of learning, and after a period of phonetic training. Main results are: (1) the perception and production of the vowels are greatly influenced by the L1 of the learners, both at the beginning and after nine months of learning; (2) the perception and production performances of the learners are better predicted by the identity of the vowel rather than its status in L2 compared to L1 (new, similar or identical vowels); (3) the phonetic training we gave showed no benefit on the perceptual or production performances of the children

Full textThis study treats the subject of contrastive experimental phonetics. It combines both the phonetic and phonological approaches in order to observe, analyze and interpret the learning difficulties encountered by Saudi learners of the vowels of French as a foreign language. The acoustical and perceptual analysis of the difficulties related to producing oral vowels by Saudi learners has enabled us to underline the particular problem of assimilating consonants with vowels encountered by these learners. Based on the conclusions of the experimental study phase, this study presents some ideas and suggestions in the field of phonetics teaching

Full textThe goal of this thesis is to better understand the phenomenon of domain-initial strengthening on French vowels: how it is realized and its linguistic function. We compare the acoustic and articulatory variations (on the lips and chin) of the French oral vowels /i, e, ɛ, a, y, ø, œ, u, o, ɔ/ in initial position of Intonational Phrase and in medial position of Intonational Phrase. The corpus was recorded by four female speakers with two different systems simultaneously. Lip aperture and lip width were analyzed from the video data and lip protrusion and lowering of the chin were captured by an optical motion capture system (Qualisys). An acoustic study was also conducted (formants, intensity, duration). Results show that initial strengthening affects phonetic properties of vowels which may contribute to enhance syntagmatic contrasts by increasing their sonority: increased lip aperture and width for all vowels, and increased acoustic intensity for most. Moreover, initial strengthening enhances vowel-specific acoustic and articulatory properties. Consequently, initial strengthening contributes to maximize paradigmatic contrasts between vowels, either by maximizing contrast of each of the values ([+F] and [-F]), either, or by maximizing the value of a single contrast ([+F] or [-F])
