Yes, it's true. His lips are saying “ga ga ga”. So how is it that when the lips are saying “ga ga ga” and the sound says “ba ba ba” that our brains read “da da da”?

The McGurk effect. It's an example of an auditory illusion. It's a great way to show that the accurate perception of information can involve the participation of more than one sensory system, in this case vision with sound. We call it multi-modal perception.

The McGurk effect. It’s a terrific example of the fact that the senses did not evolve in isolation from each other but actually work together to help us perceive our world. When multiple senses are stimulated simultaneously the brain begins to experience and information rich learning experience and laps it up like ice cream. It encodes more information per unit time and it remembers that information better too.
