Chapter 1 addresses the roles that visual information from a talker’s face can play in a communicative interaction, including the establishment of a visual connection between interlocutors, and the improvement of perceptual accuracy. In contrast to early notions that speech is perceived as an auditory signal, complemented when needed by information from other modalities (e.g., to deal with noise and/or hearing loss), research has underscored the important role of multimodal input, and emphasized the impacts of stimulus, talker, and contextual factors on the contribution of sensory cues to the perceptual outcome.
