1. A computer-implemented method of recognizing a voice input received by an interactive voice recognition system, the computer-implemented method comprising: receiving an initial caller voice input from a caller; a processor determining that the initial caller voice input is a computer-unintelligible voice input that does not match any entry from a lexicon of known voice inputs; prompting the caller to transmit a secondary input to clarify the computer-unintelligible voice input; utilizing the secondary input to match the computer-unintelligible voice input with a specific known voice input from the lexicon of known voice inputs; and updating the lexicon of known voice inputs with the computer-unintelligible voice input, wherein the computer-unintelligible voice input is matched to the specific known voice input from the lexicon of known voice inputs.
