Implementation of CIS Speech Signal Processing for Cochlear Implants by Using Bark Scale Frequency Band Partition

摘要：

A new method on the basis of Bark scale frequency-band partition was presented to improve the recognition performance of cochlear implants. In the nature of physics, it consists with humans cochlea filter properties. The mechanism of a cochlear implant and its CIS speech processing strategy were presented. Also the time-frequency analyzing property of humans cochlea was analyzed.The theoretical determination of Bark scale frequency-band was also given with formula. Simulation results using Bark scale transform signal processing were discussed in detail and results show that the new method is feasible in speech processors fcr cochlear implants.
