Literature Review on Sign Language Generation

Abstract

The deaf and dumb community uses sign language to communicate. Sign language is a language of signs including facial expressions and not of spoken words. It is a visual mode of communication. The position of hands, the movement of fingers and the expressions on the face play a vital role in sign language. Sign languages have a very limited set of words. The grammar is difficult to understand. On the contrary, spoken languages across the globe have a rich vocabulary. It is difficult for signers to understand a spoken language. There is a need to develop a system that establishes a link between spoken and sign languages. Translating from spoken languages to sign languages is a challenging task. This paper presents the state-of-the work that has been done in the field of translating English (a spoken language) to Indian Sign Language.
