Design of a lab model of a Digital Speech Processor for cochlear implant

Abstract

A cochlear implant (CI) is an el that restores partial hearing to a is profoundly deaf or severely hard of h current work, the TMS320C6713 DS implement a lab model of the cochlear im uniform band channel vocoder model. Th real-time speech input and the output excite point electrodes. As the implantatio in the inner ear is a surgical procedure, v functioning of the CI model is done simulation results. Acoustic CI simulatio implants are performed using a cepstral with Mel-frequency cepstral coeffici performance of each model depends on quality of the synthesized speech, th models were used to conduct a listen normal hearing subjects for words f database. The average grade for the channel vocoder model is found to be 3. average grade of 3.1 on a scale of 5 f vocoder model. TENCON 2011
