Özet (EN)
Cochlear implants (CI) improve partial hearing to profoundly deaf people. Many investigators from various disciplines can be made combined efforts for progression on these implants. The speech processing strategy in modern CI?s extracts and encodes amplitude information in a number of frequency bands. In this paper, we proposed an approach to improve the performance of speech enhancement techniques based on wavelet packet (WP) algorithm. To influence on speech intelligibility, the WP algorithm was modified to increase the effects of the strategies. Then this entropy based modification was applied for electrode selection.
