HTS version 2.1 includes hidden semi-Markov model (HSMM) training/adaptation/synthesis, speech parameter generation algorithm considering global variance (GV), SMAPLR/CSMAPLR adaptation, and other minor new features.

用一种显示状态驻留时间HMM（EDHMM），也称HSMM，做的一个例子，内容很详细

HSMM的计算功能实现在原来HMM的基础上解决了时间的限制，适用性更强-HSMM computing function of the original HMM solve the limit of time, on the basis of stronger applicability
