PROBLEM TO BE SOLVED: To improve the recognition rate by appropriately extracting features corresponding to a uttering speed by controlling an analytic method corresponding to the uttering speed of an input voice. SOLUTION: Concerning voices inputted from voice input means 1 and 6, the uttering speeds of the input voices are outputted by uttering speed output means 2 and 7, an analytic control parameter is determined by analytic control parameter calculations 4 and 8 by using the uttering speed and according to that analytic parameter, the features of the input voices are extracted by feature extracting means 4 and 9. |
