This selected overview of audiovisual (AV) speech perception examines the influence of visible articulatory information on what is heard. Thought to be a cross-cultural phenomenon that emerges early in typical language development, variables that influence AV speech perception include properties of the visual and the auditory signal, attentional demands, and individual differences. A brief review of the existing neurobiological evidence on how visual information influences heard speech indicates potential loci, timing, and facilitatory effects of AV over auditory only speech. The current literature on AV speech in certain clinical populations (individuals with an autism spectrum disorder, developmental language disorder, or hearing loss) reveals differences in processing that may inform interventions. Finally, a new method of assessing AV speech that does not require obvious cross-category mismatch or auditory noise was presented as a novel approach for investigators.

视听语音感知：一种新方法及其对临床人群的影响


这篇精选的视听 (AV) 语音感知概述研究了可见的发音信息对听到的内容的影响。影响 AV 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。对视觉信息如何影响听到的言语的现有神经生物学证据的简要回顾表明，AV 相对于纯听觉言语的潜在位点、时间和促进作用。目前关于某些临床人群（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 AV 言语的文献揭示了可能为干预措施提供信息的处理差异。最后，提出了一种评估 AV 语音的新方法，该方法不需要明显的跨类别不匹配或听觉噪声，作为研究人员的一种新颖方法。
