McGurk Effect

Perception and Psychophysics Effects

The McGurk effect is a perceptual phenomenon in which the auditory component of one sound is paired with the visual component of a person mouthing a different sound, causing the listener to perceive a third sound that matches neither input on its own. It demonstrates that speech perception is not purely auditory, since the visual information a person gets from watching someone speak changes what they hear.
