Patent ID: 6968310

Claim:
A speech recognition system comprising: correspondence information, said correspondence information storing a correspondence between recognized words and a plurality of speech element arrays, each array comprising associated rendering information for expressing pronunciation of said recognized words, said associated rendering information comprising at least one set of alternate renderings of a recognized word; said speech recognition system recognizing a recognizable word from a received user spoken utterance by comparing a speech element array generated from said user spoken utterance with said plurality of speech element arrays in said correspondence information; wherein, in a dialog of a single person occurring within a certain period of time, said generated speech element array corresponds to one of said plurality of speech element arrays, a pronunciation prediction probability corresponding to said one of said plurality of speech element arrays being reduced during said period of time by uniquely associating with said person one alternate rendering from the set of alternate renderings and excluding other alternate renderings from further consideration during said period of time.
