Abstract

A method for transcribing an audio response includes: A. constructing an application including a plurality of queries and a set of expected responses for each query, the set including a plurality of expected responses to each query in a textual form; B. posing each of the queries to a respondent with a querying device; C. receiving an audio response to each query from the respondent; D. performing a speech recognition function on each audio response with an automatic speech recognition device to transcribe each audio response to a textual response to each query; E. recording each audio response with a recording device; and F. comparing, with the automatic speech recognition device, each textual response to the set of expected responses for each corresponding query to determine if each textual response corresponds to any of the expected responses in the set of expected responses for the corresponding query.
