Abstract
The study investigated the initial effects of the implementation of vi brotactile support on the individual's speech perception ability. Thir ty-two subjects participated in the study; 16 with an acquired deafnes s and 16 with normal hearing. At a general level, the results indicate d no immediate and direct improvement as a function of the implementat ion across all speech perception tests. However, when the subjects wer e divided into Skilled and Less Skilled groups, based on their perform ance in the visual condition of each test, it was found that the perfo rmance of the Skilled subjects deteriorated while that of the Less Ski lled subjects improved when tactile information was provided in two co nditions (word-discrimination and word-decoding conditions). It was co ncluded that tactile information interferes with Skilled subjects' aut omaticity of these functions. Furthermore, intercorrelations between d iscrimination and decoding tasks suggest that there are similarities b etween visually and tactilely supported speechreading in how they rela te to sentence-based speechreading. Clinical implications of the resul ts were discussed.
