本文主要研究语音识别技术在机器人控制系统中的应用。机器人的语音指令仅限于一些模糊的词，比如“出发”、“上”、“下”、“右转”、“左转”等。语音识别采用了以线性预测系数（LPC）的倒易谱作为特征向量、模式比较技术和动态时间规整（DTW）等语音信号处理方法。在小型声学词汇识别应用系统中，基于LPC互反谱的模式比较方法比其他复杂算法更适用于孤立词的识别。识别是在个人电脑上实现的。将识别的语音转换为命令，通过串口RS232发送到机器人控制系统。研制了机器人语音控制系统。
This paper is about the application of speech recognition in robot control system. The robot vocal commands are limited in flfty words, such as go origin, up, down, turn right, turn left etc. The means of speech signal processing, include by taking reciprocal spectrum of Linear Predicted Coeficlent (LPC) as a eigenvector, the pattern-comparison technique and dynamic time warping (DTW), are used in the speech recognition. In a small acoustic vocabulary recognition application system, the pattern-eomparison method based on reciprocal spectrum of LPC i s more suitable than the other complex algorithm, especially in the recognition of isolated words. Recognition is realized on a personal computer. The recognized speech is converted to command, sent to the robot control system via the serial pori RS232. The voice control system of robot is developed.
