Abstract

Technological advancements have led to humans using their senses of sight, touch, and speech for various applications, control, and security. Voice control is the most powerful tool as it renders man the power to limitless applications. However, not only do the characteristics of the sound produced change variably across individuals, the characteristics of the same sound produced by one individual on repetition may also vary. Thus, there is the need for a system that can work upon any kind of sound and give the desired output for the user. The purpose of this project is to develop an audio-based application control system which uses speech, claps, snaps or any combination of the three, as inputs. This form of voice control enables users with any amputation or physical disability like blindness or deafness to perform tasks, like switching a fan on/off or sending an emergency text for help, with ease. For this project, we have developed two algorithms on MATLAB that help in detecting peaks in the input audio signal. These peaks help us to arrive at a decision as to which appliance or device is to be controlled. The decision is then sent to an AT89S52, 8051 microcontroller that is connected to a relay module. Thus, multiple appliances like air conditioner, television, telephone, light bulbs can be controlled using voice.
