Abstract

The application of cochlear implants in the correction of hearing and speech impediments in deaf persons is known more than 25 years. This paper compares 3 different speech-coding strategies. These are the multipeak (MPEAK) coding strategy, the new spectral-peak (SPEAK) coding strategy and the high-rate continuous interleaved sampling (CIS) coding strategy. Results of several investigations show that the SPEAK and CIS coding strategies, based on spectral signal analysis, allow for better speech understanding in quiet as well as in noise, than MPEAK coding strategy, which relays on speech feature extraction.
