Sign Language to Text-Speech Translator Using Machine Learning

Communication with deaf and dumb people is quite difficult task for others. So, through sign language can communicate with deaf and mute persons but it is difficult for normal people to understand the sign language hence it creates a huge gap between them and it's uneasy to exchange their ideas, thoughts with others. This gap has existed for years in order to minimize this, new technologies should be emerged. Therefore, an interpreter is necessary which acts as a bridge between deaf-mute and others. This paper proposed system which is a sign language translator. The system used American Sign Language (ASL) dataset which is pre-processed based on threshold and intensity. This system recognizes sign language alphabet and by joining the letters it creates a sentence then it converts the text to speech. As the system is based on hand, hand gesture is used in sign language recognition system, for that the efficient hand tracking technique which is given by media pipe cross platform is used and it exactly detects the hand after that by using the ANN architecture the model has trained and which classifies the images. The system has achieved 74% accuracy and recognize almost all the letters. The system which also converts sign text to speech so that it will also helpful for blind people.
