McGurk effect

The McGurk effect is a perceptual phenomenon that demonstrates an interaction between hearing and vision in speech perception. The illusion occurs when the auditory component of one sound is paired with the visual component of another sound, leading to the perception of a third sound.[1] The visual information a person gets from seeing a person speak changes the way they hear the sound.[2][3] If a person is getting poor-quality auditory information but good-quality visual information, they may be more likely to experience the McGurk effect.[4]

Integration abilities for audio and visual information may also influence whether a person will experience the effect. People who are better at sensory integration have been shown to be more susceptible to the effect.[2] Many people are affected differently by the McGurk effect based on many factors, including brain damage and other disorders.
