Development of Speech Training System for the Deaf and Its Improvement into Multimedia system

在本研究中，我们利用个人电脑开发了一个聋人语音训练系统。本实验室研制的语音训练系统已经有30多年的历史，研制的语音训练系统已捐赠给聋校。在过去的系统的情况下，数字信号处理器是一种高速计算机，被添加到个人计算机，因此，语音信号可以被真实的时间计算。然而，目前的32位个人计算机的性能比过去的数字信号处理器要好，因此，我们假设语音训练系统的信号处理可以由个人计算机本身实现真实的时间处理。另外，个人计算机系统可以利用计算机网络和多媒体系统的功能，因此，我们可以期望语音训练系统可以改进为新的系统：（1）可以实现利用计算机网络和电话线的多用户系统。(2)本研究利用真实的影像和真实的影片来呈现标准的语音模式，并提出一个以混沌为基础的个人语音训练系统，以供个人语音训练之用。

In this study, we have developed the speech training system for the deaf using the personal computer. The speech training system has been developed in our laboratory for 30 years or over, the developed systems have been donated to the deaf schools. In case of the past system, the digital signal processor that is a kind of high speed computer is added to the personal computer, therefore ; the voice signal can be computed in real time. However, the performance of the current 32 bits personal computer is better than the past digital signal processor, so, we assume that the signal process-ing for the speech training system can be realized the real time processing by the personal computer itself. In addition, the personal computer system can use the functions based on the computer networks and multimedia systems, so, we can expect that the speech training system can be improved to the new system as follows :(1) The multi-user's system using computer networks and telephone line can be realized.(2) The real image and the real movie are used for the presentation of standard pattern of speech.Furthermore, we have proposed a private communication system with chaos for the personal data transmission in the speech training.In this study, we have developed the system mentioned above, and we have plan to denote the developed system to the deaf school without payment.
