A numerical PCA-based account of tongue shapes is presented. The data are compatible with the assumption that a single context-independent control command may underlie the production of [d] as well as the front-back allophones of [g]. The findings furthermore suggest that vowel-dependent coarticulation can be seen as a form of 'incomplete interpolation' (undershoot).
