After a focus on dialectal syntax in the 1990s, an increasing interest in dialectal prosody can be noted at the beginning of the new millennium. The following findings on Swiss German prosody are based on models for a speech synthesis for the dialects of Berne and Zurich. The differences between the dialects appear not only in the phonology of intonation but - analogously to segmental phonetics - also in suprasegmental phonetics. Thus, the focus of the method lies more strongly on global phonetic aspects than on local phonological aspects. In addition to the basic conception of speech synthesis, this article discusses aspects of the analysis and certain areas of the modelling. According to the goals of the research project "Development of basic knowledge for research on Swiss German prosody by means of speech synthesis modelling" from which this paper results, findings are presented in the use of pauses, phrasing, timing aspects and intonation.
