The McGurk Effect is known as a change in auditor perception induced by incongruent visual speech, resulting in a single percept of hearing something other than what the voice is saying. This is very interesting to learn about. In the video I attached explains it very well. When they did a side-by-side it was interesting how just by looking at two different sides of the computer I heard two different things. On the left all I heard was “va” and on the right I heard “ba”. This video is very important to understand and to know the accuracy of unisensory components is reflected into audiovisual speech perception!
