Described is a program of research into sensory aids for the deaf, emphasizing research on factors involved in the effective use of sensory aids rather than evaluation of particular devices. Aspects of the program are the development of a programed testing and training unit, the control of fundamental voice frequency using visual feedback, and…

Provided is an overview of technological devices which have been designed to help the deaf with problems of warning communication (both face-to-face and at a distance), education, entertainment, and acquisition of information. (Author/LS)

The hypothesis that tactile presentation of voice fundamental frequency is as effective as auditory presentation in aiding speechreading was proven through auditory stimulation experiments, psychophysical studies, phonetic-level tactile studies, and sentence-level studies. After training with the device, three postlingually deafened adults…

An imitative test of speech pattern contrast perception was administered to profoundly deaf children using hearing aids (n=76) or cochlear implants (n=18). Implant users performed, on average, similarly to individuals with an 88 decibel hearing loss, indicating that implant use can provide auditory speech perception capacity similar to that of…
