PROBLEM TO BE SOLVED: To provide an adaptation device for effectively performing the adaptation of an acoustic model in accordance with the presence/absence and degree of a recognition error in each voice section.SOLUTION: A first alignment part reads an acoustic model, and temporally aligns read voice data and text data corresponding to the voice data on the basis of the acoustic model to generate first alignment result data including acoustic likelihood data associated with time. A second alignment part reads the recognition result data of the voice data, and temporally aligns the voice data and the read recognition result data on the basis of the acoustic model to generate second alignment result data including the acoustic likelihood data associated with the time. Then, the acoustic likelihood data of the first alignment data and the acoustic likelihood data of the second alignment result data are compared with each other, and an acoustic model is adapted while weighting corresponding to the comparison result is applied to a voice section. |
