Abstract
Two important problems in speech understanding are how to effectively integrate multiple sources of knowledge within the system and how to control the activities of the system to arrive at appropriate interpretations for utterances. This paper first describes the roles played by acoustics, syntax, semantics, and discourse, and shows how a language definition is used to integrate them into a system in a way that allows the interactions to be easily visible. The second part of the paper describes an executive that uses information from these knowledge sources in its control strategy.
