Abstract:

Audio design is a pertinent industry in today’s world, with an extremely large market including leaders such as Bose, Harman International, and Sennheiser. This project is designed to explore the processes that are necessary to create a new type of product in this market. The end goal is to have a functioning, high–quality set of speakers to prove various concepts of design and prototyping. The steps involved in this project go through the entire design process from initial choice of product to a finished prototype. Processes include the selection of outsourced components such as

Abstract:

This thesis presents the development of a software-based decoder design tool (DDT) for producing Ambisonic decoders optimised for playback over 5-speaker layouts. The research specifically focuses on developing decoders for irregular layouts with loudspeakers at a constant radial distance from the central listening position. It was motivated by the desire to provide better surround sound over the standard ITU 5-speaker layout for listeners in the sweet spot and off-centre positions. A wide-ranging literature review is presented revealing the need for such work. The DDT employs the Tabu Search

Orbit är en innovativ och tillgänglig högtalare för hemmet där upplevelse och funktion har varit kärnan i designen. Läran om ljud i rörelse kallat Kymatik har gett inspiration till att arbeta ur ett nytt perspektiv och gett ett nytt synsätt om hur ljudet rör sig. Högtalarkomponenterna har utformats med okonventionella former för att uppnå fler sätt att rikta ljud och ge uppfattningen om stort ljud från en kompakt högtalare. Miljö, erfarenhet och användare har beaktats för att skapa en långvarig användning av högtalaren. Det borde vara inspirerande och enkelt att komma närmare din musik i olika

Documentation of meetings and conferences is performed at most companies by one or more people sitting at a computer and typing what has been said during the meeting. This may lead to typing mistakes or incorect perception by the person who records. The human factor is quite large.

Abstract:

Taiwanese society perceives English as an important skill; most people expend significant efforts and resources to learn English. However, Taiwanese education focuses exclusively on traditional teaching in language courses, overlooking interactions and cultural concepts. Thus, students' ability to communicate orally in English remains relatively low. Existing literature indicates that Computer-Assisted Language Learning (CALL) can enrich language learning as computers provide many functions to enhance lectures in a meaningful and effective manner. In particular, CALL can incorporate speech rec

Abstract:

The current dissertation deals with how attenuation of information works in relation to non-nativeness. It also deals with the nature of the attenuation of information phenomenon per se. Attenuation of information refers to the fact that when words are repeated, they got attenuated in a number of ways, as in word duration, intensity, pitch, pitch excursion and pitch range. When natives speak to natives, attenuation is beneficial for comprehension as it signals the informational status of words. Also, it is known that when natives speak to non-natives, they simplify speech performing foreig

碩士<br>中華大學<br>機械工程學系碩士班<br>102<br>This thesis proposed a flexible electrodynamic planar loudspeaker with limited thickness (<<10 mm). The structure applied a very simple flexible thin film diaphragm (polyimide) electroplated with traces of copper coil, the flexible thin film diaphragm was hung above a flexible magnetic bottom frame with a cavity between them, thus forming a seamless integration of electromagnetic actuation, planar structure and flexibility. The advantage of this design is that it can be used in flexible electronics or can be deployed on the surface of any object easily, e.g. o

Abstract:

碩士<br>國立中山大學<br>電機工程研究所<br>85<br>A Text independent speaker identification system based on long-term spectral feature averaging (LTA) and Karhunen-Loeve transform (KLT) for telephone speech is proposed. This system uses basis function derived from KLT to effectively reduce the data volume and preserve most of the identification information for each speaker. A database with 61 male and 72 female mandarin speakers recorded from the telephone answering system are collected for system evaluation. By the use of the first 28 features from the 128 basis functions, it is demonstrated that the corre

碩士<br>國立中山大學<br>電機工程學系研究所<br>101<br>Identification has been an important issue in the scientific and technological circles. It can be found today in the access control systems for the facilities and the login systems for the information equipment. Utilizing digital identification of RFID patterns to recognize the authorized users is an example of access control. However, the card could be lost and maybe lent to others. Biometrics therefore can be applied to greatly enhance the security of the system. Facial feature, fingerprint, iris pattern and voiceprint are common used in biological id

碩士<br>國立成功大學<br>電機工程學系碩博士班<br>101<br>This paper proposed an application-specific integrated circuit (ASIC) architecture for speaker recognition. There are three parts of this proposed system, which is including: feature extraction module, training module, and recognition module. LPCC (Linear Predictive Cepstral Coefficients) is adopted into the proposed feature extraction module. As the characteristics of symmetrical and periodical data transmission, we design a switchable butterfly architecture to optimize the efficiency of data accessing. Moreover, this module employs the reusable mechanism

Abstract:

碩士<br>南台科技大學<br>電機工程系<br>95<br>The thesis proposes a fuzzy speaker localization recognition (FSLR) system and its applications to be as a robotic acoustic system. The hardware of the FSLR system basically contains four linear arrays in which each array is composed of four microphones and mounted on each neck side of the robot. It aims to estimate the degree relationship between the main speaker and the robot and provides the robot useful information for more effective human-robot interactions. The FSLR system can determine the location of the voice according to energy information between the m
