项目摘要

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.

我们开发了一个普通语音学的计算机辅助教学系统。为了使学生更有效地理解，我们开发了一个以发音语音学为主，声学语音学为主的普通语音学教学系统，并为实验语音学的某些部分提供了准备。我们已经准备了一个系统，通过这个系统，学生能够理解说话者如何使用发声器官发出语音，以及它们是如何归类的，人们可以根据这些模式制定一个分类框架，这对描述世界语言是有用的。我们不仅介绍了主要由关节靶区组成的传统关节部位的信息，而且还介绍了运动关节和运动方向的信息。我们已经准备了FFT、LPC、小波、ABS等频谱分析，在我们的教育系统中，为了理解声学语音研究。制作了二维声谱图、三维声谱图、共振峰跟踪图、共振峰图、基频(基音)轮廓图、倒谱分析图、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，我们已经使个人电脑可以使用这个系统的某些部分。我们为国际音标(IPA)提出了一种新的数字计算机代码系统，取代了Esling(1990)和Esling and GayLord(1993)。期望通过使用这种新的编码系统，可以改善语音库的标注、语音数据的计算机利用等情况。
