A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. In this paper we have to analysis and synthesis the Tamil words in cochlear implants using the acoustic model. The channel vocoder is developed to perform the analysis and synthesis of Tamil words. System specific parameters are analyzed by developing uniform bandwidth filter bank based acoustic CI model. Acoustic CI simulations are generated for isolated words of Tamil language. The effect of number of channels on the speech quality is analyzed and a 21-channel vocoder is found to yield the best response with minimum mean square error. The impulse train is used as an excitation source to produce the synthesized speech.
