74. The method of claim 73 wherein the step of generating the first word score includes the further steps of: performing a detailed acoustic match for the subject word based on (i) the assigned values of the probabilities and (ii) the generated labels; and evaluating the first word score for the subject word from the performed detailed acoustic match.
