The McGurk effect is an interaction between visual and auditory stimuli, thus, to explain it more directly, the sense of sight anticipates the sense of hearing. Through this effect, it is possible to say that the brain translates lip reading with experiences old ones to be able to understand what is really being said and consequently what he is listening.
To understand better, let's give you a brief example: imagine that a person is in front of you repeating the syllable “ba” and that sound is reaching your brain, along with the movement that person’s lips he does. However, if the person keeps repeating the “ba”, but changes the movement of the lip, it is possible that your brain will identify other sounds. Like “fa” in case the teeth are passing through your lips, or even “va” in case the teeth catch and release from the lips.
Being in an environment of great noise, instead of listening, people start reading lips. If we stop to think that in a show it is impossible to have sound harmony, considering the instruments and the entire audience present, it is almost impossible to be able to hear someone who does not have a microphone so that the voice stands out when noise.
In this way, the McGurk effect can cause a great deal of mental confusion in any musician, however skilled. whatever, because, because I am not listening effectively, lip reading is the only way to understand somebody.
Another situation with the McGurk effect and musicians is the perception that they can convey to their audience if they speak different languages, everything will vary according to the language.
