Abstracts: The speed of the DC Series motor will be controlled by the voice inputs/ commands. This is a voltage based speed control system, which uses the special voice recognition IC HM2007, micro controller to process the commands and control the speed. In this project, to start the motor, we use voice commands, for example 1 to start the motor. Similarly other commands like 2 to reverse the direction of rotation of the DC motor, 3 to increase the speed of the DC motor more from the 2nd level, 4 for the maximum speed of the motor. Similarly voice command 5 to stop the motor. This way the voice commands can be used to vary the speed of the motor. This is the idea behind the project.
