Signal-processing techniques for cochlear implants -: A review of progress in deriving electrical stimuli from the speech signal

The combined efforts of scientists from various disciplines have contributed to the success of cochlear implants, particularly in the restoration of partial hearing to profoundly deaf people. Signal processing has played an important role in the development of different techniques for deriving electrical stimuli from the speech signal. In this article, a review is given on the various signal-processing techniques that have been used for cochlear prosthesis over the past 25 years.
