“…Most papers investigated vowel formant measurements in speech production (Hay, Podlubny, Drager, & McAuliffe, 2017;Hualde, Luchkina, & Eager, 2017;Hübscher, Borràs-Comes, & Prieto, 2017;Ots, 2017;Rao, Sanghvi, Mixdorff, & Sabu, 2017;Yang & Fox, 2017). The authors of these papers either analyzed formant measurements at pre-selected time points (Hualde et al, 2017;Yang & Fox, 2017), average formant measurements (Hay et al, 2017;Hübscher et al, 2017), or simplified descriptions of formant contours (Ots, 2017;Rao et al, 2017). Another type of dynamic data, articulatory measurements (analyzed at the vowel midpoint), was analyzed by Pastätter and Pouplier (2017).…”
