PROBLEM TO BE SOLVED: To express an acoustic model and a language model as the same model.;SOLUTION: The acoustic model parameter learning method includes a model parameter initializing process and a model parameter updating process. In the model parameter initializing process, a model parameter for calculating a recognition score is initialized. In the model parameter updating process, a feature quantity vector is input, and an objective function based on accumulation of an inner product value of the feature quantity vector and the model parameter is given from outside. The model parameter which maximizes the objective function is calculated by updating the initialized model parameter to output a partial model parameter composed of the predetermined number of frames corresponding to each phoneme.;COPYRIGHT: (C)2011,JPO&INPIT
