The study employs an autosegmental-metrical model of intonation to propose an intonational grammar of Swabian and Upper Saxon German, respectively. The analysis is guided by the assumption that each dialect exhibits a specific distinct intonation. The phonological analysis is comparative in nature: the implementation of accents is compared between the dialects in terms of tonal alignment and excursions. In fact, the phonetic data present evidence for the phonological analysis in that the individual tonal categories differ significantly from each other. In addition, a functional analysis of the intonation contours provides further evidence for the phonological analysis. Based on the assumption that nuclear contours convey intonational meaning, these meanings are analysed and compared. A certain meaning can be attributed to intonation contours that differ phonologically between the two dialects. However, the general shape of contours and its association with meaning has been proved to be identical in the two dialects and compared to a similar analysis of intonational meaning of British English. This comprehensive study of dialect intonation contributes to improve our understanding of intonational phonology.
