In order to overcome the defects of the duration modeling of homogeneous HMM in speech recognition,a Duration Distribution Based HMM (DDBHMM) is proposed in this paper based on a formalized definition of a left-to-right inhomogeneous Markov model,which has been demonstrated that it can be identically defined by either the state duration or the state transition probabilities.
