Hearing, seeing, and feeling speech: the neurophysiological correlates of trimodal speech perception.

Introduction: To perceive speech, our brains process information from different sensory modalities. Previous electroencephalography (EEG) research has established that audio-visual information provides an advantage compared to auditory-only information during early auditory processing. In addition, behavioral research showed that auditory speech perception is not only enhanced by visual information but also by tactile information, transmitted by puffs of air arriving at the skin and aligned with speech.

Speech perception is a multi-sensory experience. Visual information enhances [Sumby and Pollack (1954). J.
