Are Articulatory Settings Mechanically Advantageous for Speech Motor Control? - Figure 4

(a) Cross-distances in more detail (lip aperture (LA), velic aperture (VEL), and constrictions of the tongue tip (TTCD), tongue dorsum (TDCD) and tongue root (TRCD). (b) Articulatory posture variables – jaw angle (JA), tongue centroid (TC) and length (TL), and upper and lower lip centroids (ULC and LLC).
