Auditory-Visual Speech Processing (AVSP'98)
December 4-6, 1998
This study investigated whether visual speech perception can be improved with short-term training. This paper first reviews the literature on lipreading training. Then a study is reported that involved 6-7 hours of lipreading training within at most three weeks. In Exp. I, subjects were adults with impaired hearing (IH) or with normal hearing (NH). They alternated training and testing on sets of prerecorded isolated sentences. Exp. II replicated Exp. I, except that subjects also received vibrotactile speech signals during training. It was hypothesized, based on previous studies, that this might promote learning. Evidence was obtained for learning in both experiments during initial test periods, primarily for the NH groups in both experiments. However, the IH group was overall more accurate. The training effects and the differential performance of IH versus NH groups imply the need to take perceptual learning and experience into account in evaluating practical applications involving visible speech.
