A novel VOCODER for cochlear implants

A new VOCODER-based speech processing strategy for cochlear implants is presented. The proposed method improves upon existing VOCODER techniques in time-frequency resolution and can offer higher noise immunity. The presented method is based on the effective tracking of nonstationary sinusoid components using a non-linear sinusoid tracking algorithm (STA). The structure of the proposed technique, as well as the underlying STA are presented. It is expected that the improvement in time-frequency resolution will offer superior performance in cochlear implants, as well as improvements in speech coding applications. An eight-band version of the proposed technique is presented and superior performance to existing techniques is shown.
