This study used Functional Data Analysis (FDA) to analyse tongue articulation dynamics, more specifically the height and frontness of the tongue body and tip in the palatal vowels /i:, y:, 0ff :/ of two varieties of Swedish. Articulatory data were collected from nine speakers each of Gothenburg and Malmohus Swedish. Standard z-score transformations were used for speaker normalisation. Results showed that the tongue articulation for /i:/ and /y:/ is generally similar, and significantly different from /0ff :/ in both Malmohus and Gothenburg Swedish. We also found a subdivision of Gothenburg Swedish into two subtypes, where type 1 resembled Malmohus Swedish more. Significant differences in tongue body height were found between all varieties for all of the vowels, except for /y:/ between Gothenburg type 1 and Malmohus Swedish.
