摘要：Through research and optimization, the accuracy of English pronunciation can be effectively improved. In the past, in the process of stripping out the mutated speech, pronunciation was analyzed according to the pronunciation intonation, so as to reduce the errors. However, the old identification model can't completely correct pronunciation errors. Therefore, in this paper, the traditional English pronunciation recognition model was optimized. Training data samples were established by collecting the pronunciation and lip movements of different people. Then according to the maximum mutual information criterion and statistic criterion, the database was analyzed, and the function of English pronunciation intonation rationality was obtained. And then combined with the dynamic time warping principle, the mistakes in the pronunciation intonation were effectively reduced. The simulation results show that the recognition accuracy of English pronunciation recognition using optimization model is higher, which provides a certain scientific basis for the teaching of pronunciation differences between England and America.
