Abstract
Systems, methods, and computer program products for determining voice recognition accuracy of a voice recognition system are provided. In one embodiment, voice recognition information produced by a voice recognition system in response to recognizing a user utterance is analyzed. The voice recognition information comprises a recognized voice command associated with the user utterance and a reference to an audio file that includes the user utterance. Based on the analysis, a recognition error may be identified and the source of the error determined. A solution is then automatically implemented to eliminate the source of the error. As part of the analysis, the user utterance may be transcribed to create a transcribed utterance, if the recognized voice command does not match the user utterance. The transcribed utterance may then be compared to the recognized voice command to identify an error.
