Abstract:     In a computer speech dictation system, a method and system for automatically determining whether to update a language model based upon user amendments to text in a dictated word processing document. The method includes the steps of monitoring a user's text-amending input to an application program for amending the dictated text and subsequently performing processing responsive to the monitoring step to determine whether the text-amending input corrects a misrecognized word in the dictated text. If the test amending input corrects a misrecognized word, the system updates a language model based upon the text which has been amended.

What is claimed is:     1. In a computer speech dictation system, a method for automatically determining whether to update a language model based upon user amendments to dictated text in a word processing document, comprising the steps of:
  • monitoring an application program for at least one text-amending input;
  • determining whether said at least one text-amending input corrects a misrecognized word in the dictated text, or does not correct a misrecognized word in the dictated text; and,
  • updating said language model based upon the at least one text-amending input if the text-amending input is determined to correct a misrecognized word.
