چکیده
The main idea of this research is to process analog voice signal. The paper is implemented for controlling the robot by voice command. The implemented system involves voice recognition unit, digital data processing unit with DC switching section. The proposed system consists of a microcontroller and a voice recognition processor that can recognize a limited number of voice patterns. This is voice based guidance system, which uses the special voice recognition IC HM2007 for speech enhancement. It also generates different desired signals according to the spoken words which further used to control the movement of robot. The microcontroller used is PIC16F877A, to give the instructions to the robot for its operation. Backup power is included in this research to retain the voice commands while the system is powered off. The R.F transmitter and receiver are used here, for the wireless transmission purpose. The constructed system can be commanded in the voice of English as well as Myanmar.
