This paper describes the structure of the SRI speech understanding system and presents the available data on its performance. The system is distinctive in the way that knowledge of various sources is coordinated by a "best-first" parser to predict the sequence of words in an utterance, and in the use of word functions–programs that represent the acoustic characteristics of a word–to test the predictions.
