Different Techniques for Hand Gesture Recognition and Speech Conversion: A Survey

Abstract

In the era of digital communication, people have various ways of communicating with each other. However, this is not the case with hearing impaired people. Hearing impaired people have no other way except for hand gestures to communicate with hearing-abled people. Digital communication is also possible if the way of communication between the communicators is same. In many parts of the world, Sign languages have different vocabulary as compared to normal language. American Sign Language is still a better-standardized version over Indian Sign Language. In emergencies such as accidents, hospitalization, it becomes very tedious for a people to communicate with a hearing-impaired person. Hearing impaired people face difficulties in every day situation due to this communication barrier. Providing a device or a way of communication that bridges this gap between a normal person and a hearing-impaired person would make their life even simpler. Any emergency can be efficiently tackled, if we have an interpreter that could understand the sign language and make us understand the meaning behind the gestures. This survey paper represents a study of some techniques for recognition of Hand Gesture to precisely interpret the hand gestures and covert them to speech.
