When identifying phonemes in new spoken words, lipreading is an important source of information for many deaf people. Because many groups of phonemes are virtually indistinguishable by sight, deaf people are able to identify about 30% of phonemes when lipreading non-words. Cued speech (CS) is a system of hand shapes and hand positions used…

Deaf children exposed to Cued Speech (CS), either before age two (early) or later at school (late), were presented with pseudowords with and without CS. The main goal was to establish the way in which lipreading and CS combine to produce unitary percepts, similar to audiovisual integration in speech perception, when participants are presented with…

Cued speech is presented as a system of phonemes and mouthshapes which can supplement speechreading. Research findings are presented on cue reception, cue comprehension, and development of sensory aids for cue presentation. Also discussed are research needs, and applications of cued speech for hearing-impaired speechreaders and for hearing…
