Abstract
Since the development of robots, voice control has been the most natural and convenient control for robot control System. From the perspective of the research status of voice recognition technology at home and abroad, communicate with robots and put voice Recognition technology applied to robots is becoming a hot topic of research.
Speech recognition technology enables robots to understand the natural language of humans, using information identified as a voice-activated signal is applied to various technical fields of robots. Applying voice recognition technology to robots brings users Great convenience. Therefore, the research and development of a practical robot speech recognition system is widely used for robots. It is of great significance. The main content of the paper is as follows:
First, based on the basic principles of speech recognition, the key to speech recognition for robot dialogue is studied.Technology, preprocessing of speech signals, including sampling, noise removal, endpoint detection, pre-emphasis, windowing separate frame and so on.; Performance of Linear Prediction Cepstrum Coefficient (LPCC) and Mel Frequency Cepstrum Coefficient (MFCC)Contrastive analysis; researched mainstream model training and pattern matching technology, which is the core of speech recognition technology Parts, including Hidden Markov Models (HMM), Dynamic Time Warping (DTW), Vector Quantization (VQ),Artificial neural network (ANN), a hybrid model of HMM and ANN, etc.
The initial robot speech recognition and control functions are implemented by matlab programming.
Keywords: Robot，Speech Recognition，Dynamic Time Warping (DTW)
