Abstract

Auditory prostheses, such as cochlear implant and auditory brainstem implant, are used clinically to restore the hearing of patients with sensorineural hearing loss. These devices can considerably improve the auditory information conveyed to the auditory cortex, but proper rehabilitation process is usually necessary to restore auditory communication to an adequate level. Therefore, improvements in the auditory information provided by the prosthesis can be complemented by better rehabilitation process. Moreover, the complementary role of visual cues is also important. The lip-reading phenomenon is well known in patients with degraded speech perception; i.e., reduced speech perception in the presence of poor auditory conditions, such as background noise and in patients with hearing loss, is improved by the combined presentation of visual speech. In addition to such conventional lip-reading, audio-visual speech has another beneficial role in the auditory rehabilitation process; i.e., the visual cue enhances the auditory adaptation process to the degraded speech sound. In the present paper, these two aspects of audio-visual speech in auditory rehabilitation are reviewed.
