PROBLEM TO BE SOLVED: To properly and effectively determine the weighted coefficients of individual evaluation values in the speech recognition device which performs weighted addition of the individual evaluation values generated from the set of the columns of the recognized acoustic units based on plural knowledge sources, integrates the results and obtains the recognition result against inputted voices. SOLUTION: An evlauation value storage section 86 stores acoustic and linguistic evaluation values. A difference evaluation value/inverse difference evaluation value computing section 87 computes difference evaluation values and inverse difference evaluation values from the stored evaluation values and a discrimination function coefficient generating section 88 computes the coefficients of a discrimination function, based on the difference evaluation values and inverse difference evaluation values. Then, the coefficients are set as the coefficients of the weighting of weighting sections 81 to 84. |
