چکیده

When a speaker talks, the visible consequences of what they are saying can be seen. This auditory (the speech sound) and visual (movements of the lips and other articulators), or AV speech influences what listeners hear both in noisy listening environments and when auditory speech can easily be heard. Thought to be a cross‐cultural phenomenon that emerges early in typical language development, variables that influence audiovisual speech perception include properties of the visual and the auditory signal, attentional demands, and individual differences. Further, the existing neurobiological evidence suggests facilitatory effects of audiovisual over auditory only speech. Studies of audiovisual speech perception in certain clinical populations (e.g., individuals with an autism spectrum disorder, developmental language disorder or hearing loss) have revealed differences in processing that may inform future interventions. Finally, a new method of assessing AV speech that does not require obvious cross‐category mismatch or auditory noise is proposed as an alternative approach to traditional measures of AV speech perception for investigators.
