Using an automatic tool for measuring and segmenting movement segments of x-ray microbeam pellet tracings, we measured various dimensions of jaw movement in the vertical direction during productions of contrastive emphasis in elicited dialogue situations. We find that the measures maximum vertical displacement and total area seem to correlate highly with contrastive emphasis, and are sufficient for differentiating between syllables spoken with contrastive emphasis and those spoken without contrastive emphasis. Moreover, these measures increase as the speaker is asked to repeat the same correction two to five times.
