“…The dash-dotted vertical line (-Á) identifies the approximate posterior boundary of the hard palate. Gridlines identified as being "in the constriction" of the vowel by the algorithm in Jackson and McGowan (2010) are plotted with "*." The double-headed arrow labeled "front" shows the region of the vocal tract acoustically modeled as the front tube.…”

“…This vocal tract constriction was characterized using the method described in Jackson and McGowan (2010). In this method, a criterion cross-distance for the constriction was defined to be 2.25 times the mean of four distances: the minimum cross-distance in the hard palate region, and the cross-distances at the three gridlines posterior to the gridline with the minimum cross-distance.…”

The purpose of this study is to test a methodology for describing the articulation of vowels. High front vowels are a test case because some theories suggest that high front vowels have little cross-linguistic variation. Acoustic studies appear to show counterexamples to these predictions, but purely acoustic studies are difficult to interpret because of the many-to-one relation between articulation and acoustics. In this study, vocal tract dimensions, including constriction degree and position, are measured from cinéradiographic and x-ray data on high front vowels from three different languages (North American English, French, and Mandarin Chinese). Statistical comparisons find several significant articulatory differences between North American English /i/ and Mandarin Chinese and French /i/. In particular, differences in constriction degree were found, but not constriction position. Articulatory synthesis is used to model the acoustic consequences of some of the significant articulatory differences, finding that the articulatory differences may have the acoustic consequences of making the latter languages’ /i/ perceptually sharper by shifting the frequencies of F2 and F3 upwards. In addition, the vowel /y/ has specific articulations that differ from those for /i/, including a wider tongue constriction, and substantially different acoustic sensitivity functions for F2 and F3.
