23. An article of manufacture comprising: a computer-readable storage medium having executable instructions thereon which when executed cause a processor to perform operations comprising: (a) recognizing utterances through converting the utterances into a recognized phone string; (b) comparing the recognized string with a reference string to determine errors; (c) calculating estimated weights for sections of the utterances; (d) marking the errors in the utterances and providing corresponding estimated weights to form adaptation enrollment data; and (e) using the adaptation enrollment data to convert a speaker independent model to a speaker dependent model; wherein the estimated weights are computed through computing an average likelihood difference per frame and then computing a weight value by averaging the average likelihood difference over error words.

The article of manufacture of claim 23 , wherein the utterances are converted into a recognized string a first time through applying the speaker independent model and thereafter through applying the most recently obtained speaker dependent model.
