Abstract
The present invention relates to a speech recognition apparatus for recognizing speeches of a plurality of users with high accuracy. An adapting unitdetects 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 unitand allocates the input speech to the best transformation function. Further, the adapting unitupdates the transformation function to which the new input speech is allocated by all the input speeches allocated to the transformation function. A selecting unitselects the transformation function used for transforming the input speech from at least one transformation function stored in the storing unitA transforming unittransforms the input speech by the selected transformation function. A matching unitperforms 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.
