ABSTRACT:
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 acoustical 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 updating step can comprise adding new words to a vocabulary in the speech application.
