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.

在本研究中，我们利用个人计算机开发了聋人语音训练系统。我们实验室开发的语音训练系统已经有30多年的历史了，所开发的系统已经捐赠给了聋校。在过去的系统中，在个人计算机上增加了作为一种高速计算机的数字信号处理器，因此，可以实时地计算语音信号。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自己来实现实时处理。此外，个人计算机系统可以使用基于计算机网络和多媒体系统的功能，因此可以预期语音培训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)使用真实的图像和真实的电影来呈现标准的语音模式。此外，我们还提出了一种用于语音培训中个人数据传输的混沌私人通信系统。
