| Abstract: | The dynamic HMM describe the relationship between dynamic property and speech to improve the performance of speech recognition. The extraction of dynamic property is important to the dynamic HMM model. In this paper, we use extended pitch contour as the dynamic property. An automatic dynamic property extraction method has been introduced. The result shows that the dynamic HMM model using extended pitch contour can improve the performance of speech recognition. |
