In order to use duration information in Language IDentification (LID) efficiently, the inhomogeneous Hidden Markov Model (HMM) with general topological structure is proposed, and is used to identify the language between Mandarin and English also.

• 为了充分利用语音信号中的段长信息,该文提出了一种具有一般拓扑结构的非齐次隐含Markov模型(Hidden Markov Model,HMM),并将其应用于中、英文语种辨识(Language IDentification,LID)系统。
