Abstract:
Purpose:Cochlear implant is a sort of device which is used to restore normal heating for the profoundly deaf by electrical stimulation of the auditory nerve.Simulation of multiple channels demonstrates that the number of channels has significant influence on sound effect.Method:This paper reviews the Continuous Interleaved Sampling (CIS) strategy for cochlear implants,and simulates it in PC.The audible sound of cochlear implanter is synthesized,and preliminary analysis of the speech identification rate of CIS strategy in different channels has also been done based on the simulation.Result:CIS strategy using 6 or 8 channels can achieve better sound effect .Conclusion:Simulation results show that CIS strategy with envelope extraction and high number of channels can produce satisfactory speech synthesis effect
