This work examines whether articulatory-acoustic relationships familiar from modelling studies are actually observable in speakers' utterances. Using electromagnetic articulography the relation between formant frequencies and constriction location and size was examined in /i/, /e/, /y/ and /ø/. F2 vs.constriction location: Correlations were close to zero. This applied to both unrounded and rounded vowels. F2 vs. constriction size: Correlations were moderately strong. However, the slope of the relationship was surprisingly flat, around 20 Hz/mm. F1 vs. constriction size: Correlations were very strong, but with flatter regression slope for rounded than unrounded vowels. Some articulatory compensation for the flatter slope in rounded vowels was observed. Implications for future work are discussed.
