Understanding coordination of the articulators in the oral cavity requires that the geometry of their motion be specified. To this end tongue and jaw movements were measured using the X-ray microbeam system. Paths (sequences of positions) of pellets attached to the tongue and mandible were examined during fast, normal and loud speech. The observed movements of the tongue were complex, exhibiting curved paths for CV transitions. The degree of curvature varied with the speaking volume. The paths exhibited by the jaw, on the other hand were straighter. When jaw motion was examined in a joint frame of reference (motion about the center of rotation of the condyle and translation of the axis of rotation along the articular eminence) it was found that the proportion of rotation and translation varied with different consonants. Finally, the influence of the jaw on the movement of the tongue surface was examined by projecting the tongue movements into a jaw coordinate space. This analysis revealed that part of the complexity of the tongue pellet paths was due to the jaw motion.
