Speech is a necessary element for every human being, importance of which is summed up into two: expression and conception. People suffering from speech disability are apprehensive while communicating with normal people and even to involve in community interaction. This paper proposes development of a wearable assistive vocalizer, designed as two distinct modules communicating wirelessly, with Gesture Sensing Module placed on wrist of person and speech synthesizing module provided with portability to either mount around waist or connect to any audio device. Every gesture is assigned one word message that is transmitted employing Amplitude Shift keying modulation at 433.92 MHz radio frequency. The error probability for receiving multiple messages that were transmitted consecutively is plotted to analyze wireless response of system.
