1. A speech recognition system comprising: a querying device for posing at least one query over a telephone to a telephone respondent; a speech recognition device that is configured and arranged to receive an audio response from said respondent over the telephone and to conduct a speaker-independent speech recognition analysis of said audio response to automatically produce a corresponding text response; a storage device for recording and storing said audio response as it is received by said speech recognition device; an accuracy determination device for automatically comparing said text response to a text set of expected responses and determining whether said text response corresponds to one of said expected responses, wherein said accuracy determination device is configured and arranged to determine whether said text response corresponds to one of said expected responses within a predetermined accuracy confidence parameter and to automatically flag said audio response so as to produce a flagged audio response for further review by a human operator, wherein the human operator is different from the telephone respondent, when said text response does not correspond to one of said expected responses within said predetermined accuracy confidence parameter; and a human interface device for enabling said human operator to hear said flagged audio response and review the corresponding text response for the flagged audio response to determine the actual text response for the flagged audio response, either by selecting from a pre-determined list of text responses or typing the actual text response if no such match exists in the pre-determined list of text responses.
