Current speech recognition algorithms designed for use in severe noise environments have demonstrated robust performance in ambient noise levels up to 97 dB for vocabularies of approximately 30 words. Robustness with respect to human speech variability due to physiological and psychological stress is still considered a limitation to widespread application of speech recognition for applications that can induce such stress. Testing for robust speech recognition performance must assess other noise environments and must address rejection accuracy as well as recognition accuracy. A rigorous measure of rejection accuracy is obtained by submitting an algorithm to tokens that differ from legal vocabulary words by a single phoneme (speech sound). The two studies reported here addressed these issues for speaker-dependent, connected speech, template matching algorithms.
