Till date blind people struggle a lot to live their miserable life. Their problems have made them to lose their hope to live in this competing society. They seek help from others to guide them whole day. This paper aims to make the blind person fully independent. The main goal of this paper is help blind and visually impaired person to find information for their everyday lives when it needed through radio station. It involves the synchronization of different sound signals and reading of each signal bit wise. These signals store in database, apply the HMM algorithm and distribute each sound signal in one information database. Speech recognition system is applies and each sound signal must create sound corresponding to it in database. .Net simulation tool is use to implement our approach. We present experiments result show how effectively it helps blind and visually impair persons.
