Electrophysiological evidence for a multisensory speech-specific mode of perception

► Is sine-wave speech (SWS) integrated with lipread information? ► Audiovisual integration occurred only when SWS was perceived as speech. ► A McGurk MMN with SWS was evoked in speech mode, but not in non-speech mode. ► Perceptual mode affects audiovisual integration at the sensory processing stage.
