13. A method for recognizing a speech utterance comprising the steps of: obtaining a word; receiving a first transcription for the word; receiving a second transcription for the word; initializing a first probability factor for the first transcription; initializing a second probability factor for the second transcription; activating the first transcription; activating the second transcription; receiving speech utterances; determining the word signified by the speech utterances; evaluating through a predetermined number of times the speech utterances against the first transcription; evaluating through a predetermined number of times the speech utterances against the second transcription; updating the first probability factor based on an accumulated acoustic score for the first transcription and a total accumulated score of the first transcription and the second transcription; updating the second probability factor based on an accumulated acoustic score for the second transcription and the total accumulated score of the first transcription and the second transcription; and inactivating the first transcription if the updated first probability factor is less than a threshold.
