This paper reflects some thoughts on pragmatics in the context of a Speech Understanding System which is currently developed at the University Erlangen-Nuernberg. After a brief outline of the system's structure with an emphasis on the characteristics of the parser and the knowledge representation scheme we present some of the underlying theoretical considerations. The main part of the paper describes the design criteria for the SEMANTICS, PRAGMATICS, and DIALOG modules, and the structure of their interactions within a general discourse understanding framework, in particular the role of a user/task model.
