Automatically improving a voice recognition system

A system for monitoring recognition accuracy of a voice recognition system having at least one recognition grammar comprising:

• software for retrieving voice recognition information stored in a call log by a voice recognition system in response to recognizing a user utterance, the voice recognition information comprising a recognized voice command associated with the user utterance and a reference to an audio file that includes the user utterance;
• a transcription log produced by the transcription software, the transcription log comprising an entry associated with the user utterance, the entry comprising:
• the recognized voice command;
• and
• a transcribed utterance produced from transcribing the user utterance, if the user utterance included in the audio file does not match the recognized voice command associated with it;
• wherein the software determines a recognition accuracy for the voice recognition system by analyzing the entry recorded in the transcription log.

A method for automatically improving a voice recognition system comprising:

• determining voice recognition accuracy by analyzing voice recognition information produced by a voice recognition system in response to receiving a user utterance, the voice recognition system comprising a recognition grammar and a first configuration, the voice recognition information comprising a recognized voice command associated with the user utterance;
• detecting a recognition error, if the recognized voice command does not match a transcribed utterance for the user utterance;
• determining at least one source of error for the detected recognition error;
• hypothesizing at least one solution to eliminate the source of error;
• and
• modifying the first configuration based on the hypothesized solution to implement a second configuration for the voice recognition system with better recognition accuracy.

A method performed on a computer for monitoring recognition accuracy in a voice recognition system comprising:

• recording a user utterance in an audio file;
• storing a voice command which was recognized by the voice recognition system for the user utterance;
• presenting the audio file and the voice command to an operator for selection;
• playing the user utterance from the audio file for the operator upon selection by the operator;
• receiving a transcription of the user utterance;
• and
• associating the transcription with the recognized voice command.
