This study examined the effects of speechreading sentence perception across three speaker viewing angles: front view, quarter view, and side view. The performance of a female adult with postlingual hearing loss was measured at each angle. Results indicated that the side view angle was the most effective, though performance at the other angles was…

This preliminary study examined effects of word visibility and prime association factors on visual spoken word recognition in lipreading, using a related/unrelated prime-target paradigm with 20 hearing adults. In related prime-target pairings, more targets with a high than low prime association were identified. In unrelated prime-target pairings,…

This study compared visual word recognition (speechreading) in video sequences showing either full face or lips plus mandible to 26 normal hearing college students and 4 adults with bilateral sensorineural hearing loss. Percent phoneme correct scores were similar in the two conditions and scores significantly improved for the repeated measure in…

Two experiments were conducted to test the hypothesis that visual information related to segmental versus prosodic aspects of speech is distributed differently on the face of the talker. Results indicate that information in the upper part of the talker's face is more critical for intonation pattern decisions than for decisions about word segments…

Lip reading is the ability to partially understand speech by looking at the speaker's lips. It improves the intelligibility of speech in noise when audio-visual perception is compared with audio-only perception. A recent set of experiments showed that seeing the speaker's lips also enhances "sensitivity" to acoustic information,…

Three methods by which hearing adults process speechread information are discussed: selective adaptation, immediate memory, and repetition priming. Also discussed are mental representations of speech by hearing-impaired and hearing children, infants' responses to speechread stimuli compared to other stimuli, infants' speechreading of a foreign…
