Personal computer based video database system of speech articulation as an aid for Japanese pronounciation learning

本研究的目的是为日语发音的外国学习者提供学习/教学视频资料。收集了日语、韩语和汉语的视频数据如下：元音和辅音的面部形象发音。舌头发元音时的超声断层摄影。纤维透视喉部发出辅音的过程。这些数据以数字视频数据的形式存储在光盘和/或个人计算机上。开发了一个程序系统，通过简单、容易的操作，在计算机屏幕上检索和显示所需的数据。同时，学习者发音的视频图像可以实时输入和显示，并可以与计算机屏幕上预先存储的数据进行比较。本系统是基于个人电脑Windows系统（Microsoft）常用的多媒体功能而开发的。

Purpose of the present study is to provide learning/teaching video materials for the foreign learners of Japanese pronounciation. Following video data were collected for Japanese, Korean and Chinese.1.Facial image of the vowel and consonant pronounciation.2.Ultrasonic tomograph of the tongue in vowel production.3.Fiberscopic view of the larynx in consonant production.These data were stored on the optical video disc and/or on the personal computer as digital video data. A program system was developed which retrieve and display desired data on the computer screen throuhgh simple, easy operation. At the same time, the video image of the learner's pronounciation can be input and displayd in real time and can be compared with pre-stored data on the computer screen. The system is developed based on the common multimedia functions of the Windows system (Microsoft) on the personal computer.
