Hearing-impaired persons usually perceive speech by watching the face of the talker while listening through a hearing aid. Normal-hearing persons also tend to rely on visual cues, especially when they communicate in noisy or reverberant environments. Numerous clinical and laboratory studies on the auditory-visual performance of normal-hearing and hearing-impaired children and adults demonstrate that combined auditory-visual perception is superior to perception through either audition or vision alone. This paper reviews these studies and provides a rationale for routine evaluation of auditory-visual speech perception in audiology clinics.
听力受损者通常在通过助听器聆听的同时，通过观察说话者的面部来感知言语。听力正常的人也倾向于依赖视觉线索，尤其是当他们在嘈杂或有回声的环境中交流时。关于听力正常和听力受损的儿童及成人的视听表现的大量临床和实验室研究表明，听觉-视觉联合感知优于单独通过听觉或视觉的感知。本文回顾了这些研究，并为听力学诊所常规评估听觉-视觉言语感知提供了理论依据。
