基于改进DTW的机器人语音指令识别系统研究
Study of Voice Command Recognition System for Robot Based on Improved DTW
摘要
Abstract
Dynamic Time Warping (DTW)is a kind of classical algorithm in speech recognition system.Because of the simple and valid,DTW method has been widely used in speech recognition,especially for the recognition of isolated word.In order to achieve the purpose of increasing the recognition rate and recognition speed of robot voice recognition system,an improved DTW speech recognition algorithm is performed here.Improved voice endpoint detection and improved DTW algorithm simulation experiment has been presented in this proposed identification algorithm in MATLAB 7.0,the experimental results show that the proposed method can improve the recognition rate and reduce the recognition time.Finally,the algorithm is transplanted to the robot,in a quiet environment the practical application turns out that the robot can quickly identify the content of the speech.In conclusion,the improved speech recognition algorithm can effectively improve the recognition rate and recognition speed.关键词
