Abstract

The present invention comprises a system and method for speech verification (Fig.6) using a robust confidence measure, and includes a speech verifier 414 which compares a confidence measure for a recognized word to a predetermined threshold value in order to determine whether the recognized word is valid, where a recognized word corresponds to a word model that produces a highest recognition score. In accordance with the present invention, the foregoing confidence measure may be calculated using the recognition score for the recognized word, a background score, and a pseudo filler score that may be based upon selected average recognition scores from an N-best list 510 of recognition candidates 512.
