The McGurk effect is a perceptual phenomenon which demonstrates an interaction between hearing and vision in speech perception. It is an illusion in which humans perceive mismatched audiovisual speech as a completely different syllable. The visual information a person gets from seeing a person speak changes the way they hear the sound. If a person is not getting good auditory information, but good visual information, they may be more likely to experience the McGurk effect.

This is really interesting. I was sure that the sound had changed, but i guess since we associate certain sounds with mouth movements that it really tricks us. I wonder if this works with other sounds too.
