Abstract
Communication Technology has taken a great leap towards the advancement. The new communication technologies evolving in the world have changed the living style of the man. One of the communication technology which has revolutionized the telecommunication sector is Voice over Internet Protocol (VoIP). The conventional VoIP applications are useful for hearing enabled persons and do not address the solution for hearing impaired. This paper envisages an application which can be used by hearing impaired persons. They communicate using a text interface and make phone calls. The application provides answers for all the cases where either one or both the users communicating are hearing impaired. This enhancement for the existing VoIP solutions would be of great help to hearing impaired people.
