Speech Information Transmission through the Artificial Hearing an Asian Languages

由于语音基频的传输质量取决于每个人工耳蜗装置的语音处理器的设置，因此需要精确测量和有效利用语音基频辨别力，为此，设计了一个人工耳蜗语音基频辨别力测试和训练的计算机辅助教学（CAI）系统。该系统采用计算机程序控制的语音合成技术，可以控制声源的基频、强度和持续时间等声学参数，并根据反应的历史有效地呈现刺激。

As the transmission quality of the fundamental frequency of speech sound depends on the setting of speech processor of each cochlear implant device, it is necessary to measure the voice pitch discriminatelity precisely and to make effective use of it. For this purpose, a computer assisted instruction (CAI) system for testing and training of voice pitch discriminability through the cochlear implants is designed. The system utilizes a computer programmed speech synthesis, in which such acoustical parameters as fundamental frequency, intensity and duration of voice source can be controlled, and present the stimulus effectively according to the history of the response.
