This paper explores the possibilities and limits of a discourse grammar applied to spontaneous speech. Most discourse grammars (. SDRT, Asher, 1993; RST, Mann & Thompson, 1988) tend to be descriptive theories of written discourse which presuppose a coherent structure. This structure is the outcome of a goal directed planning process on the part of the producer. In order to obtain a better understanding of the planning process we analyse spoken discourse elicited in an experimental setting. .
