AUTOMATICALLY UPDATING LANGUAGE MODELS.

摘要

A METHOD FOR UPDATING A LANGUAGE MODEL IN A SPEECH APPLICATION DURING A CORRECTION SESSION COMPRISES THE STEPS OF: AUTOMATICALLY ACOUSTICALLY COMPARING TO ONE ANOTHER AUDIO OF ORIGINALLY DICTATED TEXT AND AUDIO FOR REPLACEMENT TEXT; AND, AUTOMATICALLY UPDATING THE LANGUAGE MODEL WITH A CORRECTION IF THE ACOUSTION COMPARISON IS CLOSE ENOUGH TO INDICATE THAT THE NEW AUDIO REPRESENTS CORRECTION OF A MISRECOGNITION ERROR RATHER THAN AN EDIT, WHEREBY THE LANGUAGE MODEL CAN BE UPDATED WITHOUT USER INTERACTION. THE UPTADING STEP CAN COMPRISE ADDING NEW WORDS TO A VOCABULARY IN THE SPEECH APPLICATION.
