Abstract:     In a speech recognition system, a method and system for updating a language model during a correction session can include automatically comparing dictated text to replacement text, determining if the replacement text is on an alternative word list if the comparison is close enough to indicate that the replacement text represents correction of a mis-recognition error rather than an edit, and updating the language model without user interaction if the replacement text is on the alternative word list. If the replacement text is not on the alternative word list, a comparison is made between dictated word digital information and replacement word digital information, and the language model is updated if the digital comparison is close enough to indicate that the replacement text represents correction of a mis-recognition error rather than an edit.
