Abstract: The sign language is used widely by people who are hearing impaired as a medium for communication. A sign language is the composition of various gestures formed by different shapes of hand, its movements, orientations as well as the facial expressions. There are around 466 million people worldwide with hearing loss and 34 million of these are children. ‘Hearing impaired’ people have very little or no hearing ability. Hence, they use sign language for communication. Different sign languages are used by people in different parts of the world.
Compared to spoken languages they are very less in number. India has introduced its own sign language called Indian Sign Language (ISL). In developing countries there are only very few schools for deaf students. In developing countries, the unemployment rate of sensory impaired people is very high. Data from Ethnologue states that among deaf population in India, which is about one percent of total population, literacy rate and number of children attending school is very less. It goes on to state that official recognition of sign languages, increasing the availability of interpreters and providing transcription in sign languages greatly improve accessibility. Signs in sign languages are the equivalent of words in spoken languages Signed languages appear to favour.
