This paper fulfills the hardware and software design of the voice recognition system, using the Samsung’s S3C2440 and the high performance chip LD3320 designed by ICRoute. It uses multi-process mechanism to complete the speech recognition, ultrasonic ranging and PTZ control based on embedded Linux platform. At the same time, the system makes the speech recognition technology applied to multi-angle ultrasonic ranging. Through the actual testing, the system can control the direction of measure-ment by identifying the voice command, without manual intervention, and finally the measurement results play out through the voice.
