ABSTRACT:
The present invention relates to a speech recognition apparatus for recognizing speeches of a plurality of users with high accuracy. An adapting unit12detects a best transformation function for adapting an input speech to an acoustic model from at least one transformation function based on the transformation results which are obtained by transforming the input speech by at least one transformation function stored in a storing unit13,and allocates the input speech to the best transformation function. Further, the adapting unit12updates the transformation function to which the new input speech is allocated by all the input speeches allocated to the transformation function. A selecting unit14selects the transformation function used for transforming the input speech from at least one transformation function stored in the storing unit13.A transforming unit5transforms the input speech by the selected transformation function. A matching unit6performs matching processing in which the speech obtained by transforming the input speech matches the acoustic model. The present invention can be applied to speech recognition apparatuses.
