Traveling Wave Based Group Delays for Cochlear Implant Speech Processing

Cochlear implant speech processors seek to generate a neural response that mimics normal hearing. However, the cochlear phase response is generally discarded, together with other fine scale temporal aspects of sound. We sought to incorporate and compare a variety of cochlear traveling wave delays (i.e. group delays) in a clinical speech processing strategy. Traveling wave delays resulted in a significant improvement in the perception of speech in noise, a longstanding difficulty for cochlear implant patients.
