| Abstract(in English) | This paper proposes an acoustic modeling technique using multiple model structures based on a Bayesian framework for speech recognition. The Bayesian approach is a statistical technique for estimating reliable predictive distributions by marginalizing model parameters, and its effectiveness in speech recognition was reported. However, although the basic idea of the Bayesian approach is to treat all parameters as random variables, only one model structure is still selected in the conventional method. To improve the model complexity, multiple model structures should be used. The proposed method focuses on model structures integration based on the Bayesian framework in acoustic modeling. Furthermore, this paper apply the deterministic annealing EM algorithm to the optimization for constructing the appropriate acoustic models. |
