What is reading lips?
Lip reading is a communication technique that allows you to understand speech only through visual stimuli. Vocal speech includes certain specific mouth shapes for each sound; The lip reader learns to recognize and interpret these shapes. Mainly the deaf and deaf is practiced, even if someone can learn and practice this technique. Reading lips phrases is an incorrect name, as practicing also obtains traces of monitoring teeth and tongue, as well as on the stimuli of the face and body language. For this reason, it is sometimes called reading speech.
Deaf and deaf people have developed numerous techniques to understand and communicate with members of the world of hearing. The most famous is sign language, which is actually a family of languages that quietly communicated with gestures of hands and faces. Sign Language has several variations, including versions used by military and enforcement of the right for quiet communication and a touch version used to communicate with those who are deaf and blind. Sign language understanding includes not only gestures, but also facial expressions, body language and context and intention of human communication. Similarly, reading lips is only a part of the process that enables communication without the use of sound.
Reading lips is not a perfect form of communication. Reading someone of lips requires intensive concentration and even the most practiced lips readers can capture only 30 to 40 percent of the speaker meaning by monitoring lip movements. There are many sounds in the throat or back of the mouth where they cannot be read and visual indicators of many sounds seem similar. It is also unnecessary if the mouth of a person is covered or directed from the lip reader. For this reason, the sign language and writing are more convenient and complete communication methods for many deaf and deaf people.
In deaf communities, reading lips are most effectively taught to those who have heard at once. People who were born deaf may be difficult or impossible to understand and processVisual allusions of spoken speech. Hearing of people can learn technology for reasons that have nothing to do with hearing loss. For example, criminal proceedings staff can learn this as a supervision technique. It can also be useful for those who study speech therapy and related fields.
The expression that reads my lips is often used to emphasize the importance or truthfulness of what they say. President George H. W. Bush used the phrase "read my lips: no new taxes" during the 1988 US presidential elections. The line returned in the 1992 elections because the new taxes he imposed during his term seemed untrustworthy. In the 1968 2001 film: Space Odyssey , the ominous HAL 9000 computer uses reading lips to discover the plans of their human companions on Disconnect. It is irony that in the 21st century software designers teach computers to read lips as a means to improve voice recognition software.
