DEVELOPMENTAL RESEARCH FOR A COMPUTER AIDED INSTRACTION SYSTEM FOR GENERAL PHONETICS USING SPEECH PROCESSING TECHNOLOGY.

我们开发了一套通用语音学计算机辅助教学系统。为了使学生更有效地理解，我们开发了一套以发音语音学为主的普通语音学教学体系，并为部分实验语音学做了准备。我们已经准备了一个系统，通过这个系统，学生们能够理解说话者是如何使用发声器官发出声音的，以及它们是如何形成模式的，人们可以从中建立一个分类框架，这对描述世界语言很有用。我们不仅介绍了以发音靶区为主的传统发音部位的信息，还介绍了运动发音点和运动方向的信息。我们准备了频谱分析，如FFT，LPC，小波，AbS等。在我国的教育体系中对声学的认识是语音的研究。我们还准备了二维声谱图、三维声谱图、声峰跟踪、声峰图、基频（音高）轮廓、倒谱分析、声道图等。我们已经在所谓的工作站上开发了这样一个系统。为了方便使用，我们已经使该系统的某些部分可以通过个人电脑使用。我们为国际音标（IPA）提出了一种新的数字计算机编码系统，以取代Esling（1990）和Esling and Gaylord（1993）。该编码系统有望改善语音数据库标注、语音数据的计算机利用等方面的现状。

We have developed a computer aided instruction system for general phonetics. In order to make students understand more effectively, we have developed an educational system for general phonetic studies mainly based on the articulatory phonetics in addition to the acoustic phonetics, and make it possible to prepare for some parts of experimental phonetics. We have prepared a system by which students are able to understand how speech sounds are produced by speakers using vocal organs, and how they fall into patterns from which one can develop a framework of classification which is useful for the description of world languages. We have introduced the information of not only traditional places of articulation which are maily consist of articulatory target regions but also moving articulators and moving directions. We have prepared spectrum analysis such as FFT,LPC,Wavelet, AbS,etc.in our educational system for the understanding of the acoustic phonetic studies. We have prepared the two-dimentional sound spectrogram, three-dimensional sound spectrogram, formant tracking, formant graph, fundamental frequency (pitch) contours, cepstrum analysis, vocal tract diagram, etc.too. We have developed such a system on what is called work stations. In order to use it easily, we have make it possible to use some parts of this system by personal computers. We have proposed a new numerical computer code system for the International Phonetic Alphabet (IPA) instead of Esling (1990) and Esling and Gaylord (1993). It is expected that we can improve the situation of labeling of speech database, computer utilization of speech osund data, etc.by using this new coding system.
