The MATLAB Realization of Mandarin Digit String Speech Recognition

摘要

This chapter has established a mandarin digit string speech recognition system which is based on the Mel Frequency Cepstrum Coefficient and the continuous hidden markov model. The system's preprocessing of speech signal, the characteristic parameter extraction, the training of the model, and the recognition algorithm is discussed in this chapter. Meanwhile the system has carried on the simulation and analysis using MATLAB pronunciation toolbox voice box. Some results of the recognition system are given. Several directions for improvement of the system are proposed in the end this chapter.
