This contribution represents cooperative work with a model for Standard Swedish prosody, specifically intonation, in a text-to-speech framework. In the present study we have focussed on the problem of phrasing. A small database of sentences, potentially ambiguous with respect to phrase boundary location, have been recorded and analysed. Considerable variation in phrase and clause boundary realizations was observed. We have identified and explored several alternative boundary signalling strategies that have the function of disambiguating the synthetic versions of our database sentences, whereby both connective and demarcative means have proved to be efficient. The new phrasing strategies add to the naturalness and fluency of the synthetic speech.
