Acoustic simulation experiments with preprocessed speech for an 8-channel cochlear implant.
A speech processor for simulation of preprocessed speech in cochlear implantation has been developed. An acoustic simulation of spectrally reduced speech was presented to 169 normally hearing subjects. Several perceptual tests with 9 different filter conditions were carried out. The intelligibility of sentences and the discrimination of phonemes in nonsense syllables were measured. It was established that even within one test session, an important learning effect occurred.
