VOICE ENABLED SPEED CONTROL OF AC MOTOR

Communication plays a major role in day today’s life and can be used as a better tool in control systems. It deals with wire communication and is used to control the motor speed. Out of all mechanisms, microcontroller hardware description language proves to be efficient than al other mechanisms. Digital means of controlling gives accurate results compared to the approximation of analog systems. Embedded technology is a key role in integrating the different functions connected with it. This proposal generally reduces the manpower, operates efficiently and saves time without human involvement. With the advancements in technology, the existing systems are developed to have in built intelligence. Due to the technological development whether it is DC or AC machines the speed of the machine can be controlled by various methods. By means of the voice process the machine can be controlled depending upon the application wired or in order to transmit the signal the wireless communication can be used. By this way electrical technology is combined with communication technology and computer science. Now a day it is very important thing to reduce the manual error and manual operation.
