Abstract

The Tickle Talker(TM) is an electrotactile speech perception device. Subjects were evaluated using the device in various tactile-alone and tactile - visual contexts to assess the generalization to other contexts of tactile-alone perceptual skills. The subjects were from a group of six normally hearing subjects who had previously received 12 to 33 h of tactile-alone word recognition training and had learned an average vocabulary of 50 words [Galvin et al., J. Acoust. Soc. Am. 106, 1084-1089 (1999)]. The tactile-alone evaluation contexts were sentences, unfamiliar talkers, and untrained words. The tactile - visual evaluation contexts were closed-set words, open-set words, and open-set sentences. Tactile-alone perceptual skills were generalized to unfamiliar speakers, sentences, and untrained words, though scores indicated that generalization was not complete. In contrast, the generalization of skills to tactile - visual contexts was minimal or absent. The potential value of tactile-alone training for hearing-impaired users of the Tickle Talker(TM) is discussed. (C) 2000 Acoustical Society of America.
