摘要
该设计运用三星公司的S3C2440,结合ICRoute公司的高性能语音识别芯片LD3320,进行了语音识别系统的硬件和软件设计。在嵌入式Linux操作系统下,运用多进程机制完成了对语音识别芯片、超声波测距和云台的控制,并将语音识别技术应用于多角度超声波测距系统中。通过测试,系统可以通过识别语音指令控制测量方向,无需手动干预,最后将测量结果通过语音播放出来。
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.
