Abstract (Swedish)
This study compares the acoustic realisation of /iː yː ʉː uː/ in
three varieties of Swedish: Central Swedish, Estonian Swedish, and Finland Swedish. Vowel tokens were extracted from isolated words produced by six elderly female speakers from each variety. Trajectories of the first three formants were modelled with discrete cosine transform (DCT) coefficients, enabling the comparison of the formant means as well as the direction and magnitude of the formant movement. Cross- dialectal differences were found in all measures and in all vowels. The most noteworthy feature of the Estonian Swedish long close vowel inventory is the lack of /yː/. For Finland Swedish it was shown that /iː/ and /yː/ are more close than in Central Swedish. The... (More)
