Determining speech recognition accuracy
First Claim
Patent Images
1. A method of determining the accuracy of a speech recognition system comprising:
- identifying from a log of said speech recognition system a text result and attributes associated with said text result, wherein said log comprises a plurality of log entries, each log entry correlated with a different electronically stored audio segment defining an audio representation corresponding to a portion of text for which a text result and at least one attribute is provided, and wherein each attribute characterizes at least one of a configuration of the speech recognition system, a type of audio channel over which an audio segment is received, and whether the audio segment is received in response to a user prompt;
accessing an audio representation from which said text result was derived;
processing said audio representation with a reference speech recognition engine to determine a second text result; and
comparing said text result with said second text result to determine an accuracy of said speech recognition system.

Abstract
A method of determining the accuracy of a speech recognition system can include identifying from a log of the speech recognition system a text result and attributes associated with the text result. An audio representation from which the text result was derived can be accessed. The audio representation can be processed with a reference speech recognition engine to determine a second text result. The text result can be compared with the second text result to determine an accuracy of the speech recognition system.
