1. A method of capturing an utterance in a voice recognition system, comprising the steps of: accepting the utterance if a first predefined relationship exists between at least one comparison result for the utterance with respect to a stored word and at least one difference between the at least one comparison result and at least one other comparison result between the utterance and at least one other stored word; applying an N-best algorithm to the utterance if a second predefined relationship exists between the at least one comparison result and the at least one difference between the at least one comparison result and the at least one other comparison result; and rejecting the utterance if a third predefined relationship exists between the at least one comparison result and the difference between the at least one comparison result and the at least one other comparison result.
