7. A computer-implemented method for adapting a speech recognition system, comprising: detecting a user-initiated change to dictated text; automatically assigning a categorization to the user-initiated change to the dictated text, the categorization being automatically assigned based at least in part upon a measurement of time indicative of how long it took the user to initiate the change, wherein automatically assigning the categorization comprises automatically identifying, based at least in part upon the measurement of time, the user-initiated change as being either a correction or an edit operation; calculating a distance between a pronunciation of the dictated text and a pronunciation of the change to the dictated text; comparing the calculated distance to a threshold value; and selectively adapting the speech recognition engine depending upon the categorization and the calculated distance, and wherein selectively adapting further comprises determining a number of times that the pronunciation of the change to the dictated text has occurred and then selectively adapting the speech recognition engine when the number of times exceeds a selected number of times.

The method of claim 7 , wherein selectively adapting comprises not adapting if the categorization indicates that the user-initiated correction is not due to a recognition error made by the speech recognition engine.
