Sagittal-plane movements of small markers attached to the upper and lower lips were analyzed for ten speakers of American English, and seven speakers of Japanese. Each speaker produced simple utterances containing vowels and labial consonants. The data were analyzed to better understand: (1) patterns of pellet motions associated with labial consonant production; (2) pellet positions at discrete, acoustically defined moments during selected speech sounds; and (3) the relationship between midline separation between the lip surfaces and inter-lip-pellet distance. Results from the study provide qualitative information about the dynamics of labial gestures for consonants involving lip closure. The data also indicate that the English and Japanese speakers positioned and moved their lips in generally similar ways during the test sounds analyzed. Finally, results suggest that plausible estimates of mid-line inter-lip separation can be derived from the trajectories of two pellets, one on each lip, as long as the possibility of lip-body deformation is taken into account
