We have developed a compound hearing aid system based on a speech analysis and synthesis model. The system is a new hearing aid one to be executed various conventional hearing aid processing selectively or simultaneously. In 1999, we have investigated a whole algorithm theoreticauy. Especially, it was confirmed that a frequency warping and a level compression had an effect on the naturalness of pitch converting speech. As results, it has been capable of defining a function between a frequency warping coefficient and a pitch conversion ratio. In 2000, we have investigated an algorithm for a speech rate control, which consisted of a local conversion and a global one temporally. And a VUS decision, which was an important factor of qualities of re-synthesized aid speech, has I been investigated also. Moreover, an evaluation system was realized on WINDOWS. As result, it has made an available of on-line evaluation tests. However, real time simulation on DSP system has not j been realized at present. In future, we are planning to device a real-time operation system based on i a board using a DSP chip, which has been purchased.

我们开发了一个基于语音分析和合成模型的复合助听器系统。该系统是一种可选择性地或同时执行多种常规助听器处理的新型助听器。1999年，我们从理论上研究了一个完整的算法。特别地，证实了频率弯曲和电平压缩对音调转换语音的自然度有影响。结果，能够定义频率弯曲系数和音调转换比之间的函数。在2000年，我们研究了一种用于语音速率控制的算法，该算法包括局部转换和全局时间转换。并对影响合成语音质量的一个重要因素VUS判决进行了研究。并在WINDOWS平台上实现了一个评价系统。因此，它提供了在线评估测试。但目前还没有在DSP系统上实现真实的实时仿真。今后，我们计划使用已购买的DSP芯片，在i a板上设计实时操作系统。
