Abstract


With the continuous development of speech recognition technology , voice control also will get the attention of a growing number of technical staff . Voice control technology, the key is to not only understand the people in what to say , but also to allow the robot to know what to do to make the robot . This article is based on the voice control technology for small vocabulary isolated word speech recognition system . This thesis discussed mainly from two aspects discussed the acoustic model of the principles of the voice recognition and voice , on the one hand, from a theoretical point of view , and study binding principle and the acoustic model for small vocabulary , isolated word recognition systems , the main part of the algorithm . On the other hand , the system from the point of view of the soccer robot platform and software platform described . Mainly three major parts of the system 's voice recognition algorithm : endpoint detection, feature parameter extraction , template matching . Endpoint detection part , isolated word recognition system for small vocabulary of short-term energy , short-time zero-crossing rate algorithm algorithm and simulation results , on this basis , and its improved algorithm simulation experimental data to make a comparison of the algorithm . Feature extraction part , this paper introduces three speech features : linear predictive coding coefficients , linear predictive coding cepstral coefficients and Mel frequency cepstral coefficients , simulation experiments were carried out on three algorithms , and algorithm comparison . Template matching part , that the identification part , this paper discusses the dynamic time warping algorithm , the improved algorithm of dynamic time warping and hidden Markov model algorithm . Because the system is based on a small vocabulary isolated word recognition algorithm improved algorithm based on template matching of dynamic time bending . VC-MATLAB mixed programming software platform for voice control of soccer robot car experiment achieved better recognition control effect .
