The linguistic knowledge of Putonghua pronunciation was effectively introduced into the calculation of HMM based log posterior probability. 新算法在隐马尔科夫模型的对数后验概率算法基础上，引入普通话发音的语言学知识。
Second, with the posterior probability weighting of the uncertain parameters, an augmented system is obtained for the uncertainty model. 其次，将此不确定性模型通过不确定参数的后验概率加权，得到其增广系统。
