See Sound Live is an assistive technology developed by 4S Medical Research P Ltd, with the help of funding from Govt. of India (BIRAC IIPME Grant 2017, SBIRI Grant 2019). The technology enables a deaf child or adult, develop near normal speech by giving the user, visual feedback of his speech efforts on a smart phone like device. The visual feedback substitutes the absent auditory feedback in deaf people that prevents them from developing speech. Results so far have been astounding. This has never been done before anywhere in the world. International patent application for See Sound Live has been completed in 2018. The product is ready for commercial deployment and is planned for launch in India in 2019-20.
