18. A computer system comprising: a processor, a computer readable memory, and a non-transitory computer readable storage media; first program instructions to receive an unintelligible voice input from a caller, wherein the unintelligible voice input is unintelligible to a computer due to background noise at a caller environment of the caller; second program instructions to determine that the unintelligible voice input does not match any entry from a lexicon of known voice inputs; third program instructions to prompt the caller to transmit a secondary input to clarify the unintelligible voice input, wherein the secondary input is a non-verbal electronic input that identifies a user-requested activity that the caller was requesting when transmitting the initial caller voice input; fourth program instructions to utilize the non-verbal electronic input to match the unintelligible voice input with a specific known voice input from the lexicon of known voice inputs; fifth program instructions to compare the unintelligible voice input to the specific known voice input to derive a voice input match percentage, wherein the voice input match percentage describes how closely the unintelligible voice input and the known voice input match one another; sixth program instructions to, in response to the voice input match percentage exceeding a predetermined value, update the lexicon of known voice inputs by adding the unintelligible voice input to the lexicon of known voice inputs, wherein the unintelligible voice input is matched to the specific known voice input from the lexicon of known voice inputs; seventh program instructions to match the unintelligible voice input to the user-requested activity in a database that is specific for the caller; eighth program instructions to receive the unintelligible voice input in a subsequent phone call from the user; and ninth program instructions to match the unintelligible voice input to the user-requested activity for the caller; and wherein the first, second, third, fourth, fifth, sixth, seventh, eighth, and ninth program instructions are stored on the non-transitory computer readable storage media for execution by the processor via the computer readable memory.
