Talkers vary widely in the ease or difficulty with which they can be speechread. Examined are variables contributing to visual intelligibility, comparisons with auditory intelligibility, the range of talker differences, characteristics accounting for these differences (facial cues, extrafacial gestures, rate, and rhythm), and implications for…

Hearing-impaired speechreaders use linguistic context to compensate for the poor visibility of some speech movements. Constraints on spoken language enhance speechreading performance and help compensate for the paucity of sensory data. The largest effects come from linguistic constraints imposed by sentence context--syntactic, semantic, and…

Research is reviewed on auditory-visual speech perception of hearing-impaired individuals. The review focuses on: the effects of competing noise, filtering, age, stimulus and noise, and hearing loss on perceptual behavior; bisensory communication evaluation procedures; and remediation of bisensory perceptual problems through consonant recognition…

VISUAL AND AUDITORY CUES WERE TESTED, SEPARATELY AND JOINTLY, TO DETERMINE THE DEGREE OF THEIR CONTRIBUTION TO IMPROVING OVERALL SPEECH SKILLS OF THE AURALLY HANDICAPPED. EIGHT SOUND INTENSITY LEVELS (FROM 6 TO 15 DECIBELS) WERE USED IN PRESENTING PHONETICALLY BALANCED WORD LISTS AND MULTIPLE-CHOICE INTELLIGIBILITY LISTS TO A SAMPLE OF 24…
