In this paper, we present a model for the analysis and synthesis of intonation in spontaneous conversations in Swedish. The model is implemented in a computational environment, making it possible to generate F0 contours, which can be imposed on a speech waveform using the PSOLA technique. Testing and exploration of this analysis-by-synthesis system on spontaneous conversational speech have led to recent extensions in the analytical framework, as well as in the actual realisation of the prosodic transcription as F0 contours. In earlier versions of the model, phrase boundaries were treated similarly for all phrases, but now we make a distinction between a minor and a major boundary. Different intonational characteristics of the type of phrase boundary have consequently been implemented. We have also introduced a rule of downstepping, which is realised by successively lowering the valleys after the pitch gesture of an accented syllable.
