New recordings of articulatory movements of the tongue, lips, and mandible have been obtained using the University of Wisconsin x-ray microbeam system, from eight normal adult speakers of American English who uttered three-number sequences in question-answer pairs such as “Is it 995 Pine Street? No, it's 955 Pine Street.” Analysis of these data is intended to provide a detailed characterization of the implementation of contrastive emphasis observed in this context. Preliminary comparisons of maximum displacements and peak velocities for the tongue blade and lower lip, during the words “nine” and “five,” respectively, show that both movement parameters increase during a syllable under the influence of contrastive emphasis, but that the relative change in articulator displacement is always greater. This observation is at least partly consistent with results of previous research [Fujimura and Spencer, J. Acoust. Soc. Am. Suppl. 1 74, S117 (1983)], which showed that maximum articulator displacements during emphasized and unemphasized vowels differed more than did certain portions of the movements toward and away from those vowels.
