This paper describes the procedures for integrating knowledge from different sources in the SRI speech understanding system. A language definition system coordinates–at the phrase level–information from syntax, semantics, and discourse in the course of the interpretation of an utterance. The system executive uses these contextual constraints in assigning priorities to alternative interpretations, combining top-down, bottom-up, and bidirectional strategies as required.
