The research reported here is conducted within the recently initiated project 'Prosodic Segmentation and Structuring of Dialogue'. The object of study in the project is the prosody of dialogue in a language technology framework. The specific goal of our research is to increase our understanding of how the prosodic aspects of speech are exploited interactively in dialogue - the genuine environment for prosody - and on the basis of this increased knowledge to be able to create a more powerful prosody model. In this paper we present an overview of project design and methods.
