Conversion of voice into sign language

Abstract

Communication is a primary human need and language is the medium for this. Most people have the ability to listen and speak and they use different languages like Urdu, Swedish, English etc. to communicate. Hearing impaired people use signs to communicate. Pakistan Sign Language (PSL) is the preferred language of the deaf persons in Pakistan. Currently, human PSL interpreters are required to facilitate communication between the deaf and hearing; they are not always available, which means that communication among the deaf and other people may be limited or non existent. In this situation, a system with voice recognition as an input and PSL as an output is required to facilitate both the normal people and the deaf people. Wherever communities of deaf people exist, sound to sign languages need to be developed. It is important that developing tools are in native language which is easy to understand. So in the system developed in this project the input is taken in Urdu sound language and the output can involve simultaneously combining hand shapes, orientation and movement of the hands to express the input words. The developed system has two parts, one is training and other is communication. In training part the system is trained for the voice and words of a new user and then the communication mode can be used for the communication purpose. The main idea is that we have to get the particular Urdu sound as an input. Computer will analyse these input sounds and synthesizes the sign as output for the corresponding word or letter for deaf people to understand
