当演讲者讲话时，他们所说的话所产生的明显后果是显而易见的。这种听觉（语音）和视觉（嘴唇和其他发音器官的运动）或 AV 语音会影响听众在嘈杂的聆听环境中以及在很容易听到听觉语音时听到的内容。影响视听语音感知的变量被认为是典型语言发展早期出现的跨文化现象，包括视觉和听觉信号的特性、注意力需求和个体差异。此外，现有的神经生物学证据表明视听比纯听觉言语具有促进作用。对某些临床人群（例如，患有自闭症谱系障碍、发育性语言障碍或听力损失的个体）的视听言语感知的研究揭示了处理方面的差异，这可能为未来的干预措施提供信息。最后，提出了一种评估 AV 语音的新方法，不需要明显的跨类别不匹配或听觉噪声，作为研究人员 AV 语音感知传统测量方法的替代方法。
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 (eg, 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.
