“…the F3 is lowered in the "r-colored" varieties of American English (see also Eklund and Traunmüller, 1997;Jongman et al, 1989;O'Brien and Smith, 2010;Chung et al, 2012), which points to possible effects of variety on the F3 (Harrington, 2010). Although the F3 is less understood than the F1 and F2 (see Adank et al, 2004;Leinonen, 2010), a number of studies show that the segmental context can have significant effects on the F3 (Harrington, 2010), and in languages with round vowels, such as in Swedish, the F3 can distinguish the rounded vowels from the nonrounded ones (Fujimura, 1967). To examine whether the SMG and CG vowels differ with respect to rounding, this study controls the segmental environment of vowels.…”
