What is McGurk effect?
McGurk Effect is a principle involved in understanding human language. The essence of the effect is that visual allusions play an important role in the understanding word of the listener. People depend on the mouth and shape of the face and hearing to understand the meaning of the speaker; In the absence of this information, it is probably incorrect communication. The effect was first documented by scientists Harry McGurk and John MacDonald in 1976. Sometimes it is called McGurk-MacDonald Effect. The deaf and hardly hear people hearing lips for centuries. An experienced lips reader raises most of the meaning of the speaker by monitoring the mouth and facial movements. Doctors and scientists who study this phenomenon soon realized that they also apply to individuals with normal hearing. This means that all people unknowingly practice the form of lips reading during the daily converting course.
McGurk effect is easily observed. In a normal conversation, the listener follows the face of the speaker. If the listener turns away, it requires a greater concentration to follow the speaker's words, and someThe sentences may need to be repeated. When the loudspeaker's face is visible, the listener will depend on the movement of the face and mouth, the context and the intention of the speaker to fully understand the speech. This concept, universal for all spoken languages, is well known for the deaf community in the world and also plays a role in sign language.
Scientists can thoroughly demonstrate the effect of McGurk with computer speech speech simulators. These programs project the image of a human face that is coordinated with pre -programmed spoken phrases. Unlike human speakers, they can also be programmed to choose the visual shape of a sound other than the one that is spoken. When the happens, listeners probably perceive the third sound completely. This has been observed, even if the listeners know what the simulator is doing, suggesting that the effect of McGurk is rooted deep in human consciousness.
McGurk effect has been the subject of computer with a computer withPecialists working on voice recognition software. It seems likely that McGurk Effect must fully understand the huge nuances of human speech. Programs in development will use a small camera to observe the movements of a person's face when they say. The computer then integrates this information into the recorded sound for a more accurate understanding of the spoken command.
