Use of preprocessor with frequency amplitude modulation encoding (Fame) for speech quality enhancement in cochlear implant to aid hearing impairment

Abstract

Cochlear Implant is a powerful technical device that facilitates hearing sensation to aid hearing in deaf or partially deaf persons. In this paper a novel method of adopting a preprocessor and using its output for Frequency Amplitude Modulation Encoding (FAME) technique has been studied. This enables filtering of noise from speech before sending it to the electrodes of Cochlear Implant. Preprocessor with FAME gives better results when compared to other techniques which are used for noise removal from the speech for Cochlear Implant users. Also this technique gives a completely new and better speech perception to the Cochlear Implant (CI) users.
