【摘要】 随机轨迹模型是针对基本隐马尔可夫模型所隐含的三个不合理假设而提出的统计建模方法。本文介绍了随机轨迹模型相对于基本隐马尔可夫模型的优越性 ,综述了以音素为语音识别基元的随机轨迹模型的理论机制和参数估计方法更多还原

【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.更多还原
