ABSTRACT: Cochlear implant bypasses damaged hair cells and stimulates the auditory nerve directly in the cochlea. Wavelets are especially useful for speech processing of CI, since in the case of wavelets one speaks of a constant-Q filter bank as well as the cochlea. In this paper, a continuous wavelet has application in the filter bank design and an effective result is obtained. Also the lifting scheme, the so-called second generation of wavelet, is adopted, combined with pitch extraction algorithm, to extract fundamental frequency of speech signal. Veracious result is obtained, which shows the great potential of wavelet an lifting scheme in the application in speech processing strategy for cochlear implants based on characteristics of Chinese language

ABSTRACT: A cochlear implant is a new device to be implanted in the inner ear and restore partial hearing to profoundly deaf people. This article first presents the acoustic simulation principle based on CIS speech processing strategy, and then proposes an improved speech synthesis model of this acoustic simulation. Finally, on the basis of acoustic simulation experimentsâ–ˇresults on normally hearing listeners, we get a close speech recognition to the result of implants patients, and suggest that our improvement be effective on evaluating cochlea processing strategies.
