The speech-induced cochlear potential (SICP) research technique is well adapted to a variety of clinically oriented questions involving processing of intelligible speech through the auditory periphery. It also provides a highly controllable means of comparing different prosthetic devices, and because it constitutes a form of "bioassay," the technique may provide the needed biological standards for reporting hearing aid response data.
With technical advances it may be possible, in the future, to record speech from human cochleas during electrocochleography and utilize the resulting SICP speech discrimination scores for additional diagnostic and rehabilitative information.
