Abstract

A single-channel vibrotactile aid providing voicing duration and intensity cues was evaluated with an experienced vibrotactile aid user as the experimental subject. The results obtained showed significant improvements in lipreading performance at the phoneme, word and sentence levels when the tactile aid supplemented the visual signal. Significant improvements were also obtained in aided connected discourse tracking. Tests of tactile perception of selected segmental and suprasegmental features showed the value of the aid in detecting word syllable number and type, contrastive stress in sentences, syllabic structure of sentences and final consonant contrasts. The aid also provides information enabling identification of a range of environmental sounds. The implications of the results obtained are discussed and future research directions outlined.
