Abstract

Two experimental groups were trained for two hours with live or recorded speech that was noise-vocoded and spectrally-shifted, and was from the same text and talker. These two groups showed equivalent improvements in performance for vocoded and shifted sentences, and the group trained with recorded speech showed consistently greater improvements than untrained controls. Another group trained with unshifted noise-vocoded speech improved no more than untrained controls. Computer-based training thus appears at least as effective as labor-intensive live-voice training for improving the perception of spectrally-shifted noise-vocoded speech, and by implication, for training of users of cochlear implants.
