Mute input device Vocalizer could be a massive scale microcontroller based mostly system being designed to facilitate the communication among the dumb and deaf individuals by manufacturing a speech and text signal. This system can be dynamically reconstructed to work as a “smart device”. In this paper, microcontroller and sensors based mute keypad vocalizer is presented. Mute keypad vocalizer discussed is basically a speaker and a keypad equipped microcontroller based system. Keypad sensor can detect the pressing of keys and microcontroller based system converts some specified key values into speech signals. The vocalizer is equipped with a keypad module and an audio processing unit. This system is beneficial for dumb and deaf people.
