Abstract
A system for generating a signal proportional to the useability of the output of a speech recognition system comprises a processor, an engine, and a histogram object. The histogram object comprises a first histogram constructed from the confidence scores of correctly recognized utterances and a second histogram constructed form incorrectly recognized utterances. The present invention also includes a system and method for constructing the histogram object comprising a processor, a data memory, and an engine. The data memory comprises a plurality of output records where each output record contains the confidence score for an utterance recognized by the speech recognition system and an indicator of whether or hot the speech recognition system correctly recognized the utterance.
