Two New Directions in Speech Processor Design for Cochlear Implants

Two new approaches to the design of speech processors for cochlear implants are described. The first aims to represent “fine structure” or “fine frequency” information in a way that it can be perceived and used by patients, and the second aims to provide a closer mimicking than was previously possible of the signal processing that occurs in the normal cochlea.
