In this paper, the authors dealing with voice recognition based door control system. MATLAB software and embedded hardware is interfaced together to form a complete module. Commands are given in MATLAB which is converted into embedded C using USB to UART (Universal Asynchronous Receiver/Transmitter) module. The voice command is checked by MATLAB software and the door is controlled by the controller using motor driver L239D. The controller gives proper output to control the door and other interface and communicate with PC.
