16. The method of claim 5 wherein the determining of the minus count values includes the steps of: (v) for a subject count used in deriving a probability value for a probability item in the incorrect word, determining a first value indicating the expected occurrence of the event corresponding to the subject count in the model of the incorrect word based on the outputs generated in response to utterance of the known word; (w) scaling the first value by a predefined amount; (x) the scaled value representing the minus count value for the subject count; and (y) repeating steps (v) through (x), until each count used in deriving a probability value for a probability item in the incorrect word model has been the subject count in at least one repetition.
17. The method of claim 16 wherein the determining of the plus count values includes the steps of: (aa) for a subject count used in deriving a probability value for a probability item in the incorrect word, determining a first value of the event corresponding to the subject count in the model of the incorrect word based on the outputs generated in response to utterance of the known word; (bb) scaling the first value by a predefined amount; (cc) the scaled value representing the plus count value for the subject count; and p1 (dd) repeating steps (aa) through (cc), until each count used in deriving a probability value for a probability item in the incorrect word model has been the subject count in at least one repetition.
