The Development of Siz-channel Speech Processor for Cochlear Implant Based on DSP
Cochlear implant devices have been developed over the years. The purpose of the present work is to develop flexible product with high reliability and reasonable price. In this paper, the principle of cochlear implant and speech processor was first introduce. And then describe the Electronic design of the six-channel speech processor for cochlear implant particular. The components of the speech processor were enumerate as the type of chip which have been chosen. The speech coding based on DSP is the most important step in the speech processor for cochlear implant. Caused different processing strategy has different effect in different patient. In this paper, ATF coding has been realized. Finally, the result of the six-channel speech processor for cochlear implant had been discussed.
