| Abstract: | Stochastic trajectory models can effectively overcome the three unreasonable assumptions caused by basic hidden Markov models.This paper introduces the advantage of stochastic trajectory models,and makes a review on the theory and the parameter estimation method of stochastic trajectory models based on phoneme. |
| |
| Keywords: | phoneme component trajectory parameter estimation |
