1. A method of updating speech models for speech recognition, comprising the steps of:

  • identifying speech data for a predetermined set of utterances from a class of users, said utterances differing from a predetermined set of stored speech models by at least a predetermined amount;

    collecting said identified speech data for similar utterances from said class of users;

    correcting said predetermined set of stored speech models as a function of the collected speech data so that the corrected speech models are an improved match to said utterances than said predetermined set of stored speech models; and

    updating said predetermined set of speech models with said corrected speech models for subsequent speech recognition of utterances from said class of users.
