The analysis of spoken dialogs requires the analysis of complete multi-sentence turns. Especially, the segmentation of turns in sentential or phrasal segments is a problem. In this paper we present a system for turn analysis. It is based on an extension of HPSG grammar for turns and takes into account extra-linguistic prosodic information. We show how this information can be integrated and represented in the grammar, and how it is used to reduce the search space in parsing.
