An improved speech processor for a 22-electrode cochelar implant [Abstract]

This is a publisher’s version of an abstract from the Annual and General Scientific Meeting of the Australian Society of Otolarngology Head and Neck Surgery, 1992. This version is reproduced with permission from Australian Society of Otolaryngology Head and Neck Surgery.A spectral maxima speech processing strategy ( SMSP) has been developed as a result of research to improve the speech perception performance of a multiple-channel cochlear implant. With this speech processing strategy. the six spectral maxima from the outputs of 16 band pass filters are used to stimulate the cochlea on a place basis at a constant rate. This SMSP strategy has been compared with the MSP-MULTIPEAK strategy, the present speech processor provided by Cochlear Pty. Limited, on four postlinguistically deaf adults. The study showed that the SMSP strategy was significantly better than the MSP-MULTJPEAK for the recognition of closed-set vowels and consonants, and open-set monosyllable words and sentences in background noise
