Effects of phrasing and word emphasis on transitional movements—Location and stability of tongue blade iceberg patterns

In previous ASA meetings, it was suggested that certain movements of an articulator that is crucial for both CV and VC identities were often observed unaffected in their nearpeak parts as stable fragmental time functions, even when large variation in other portions such as vowel portions was introduced by prosodic control. By an automatic procedure, we have identified the parts of demisyllabic transitions that are likely to be stable under manipulation of phrasing such as (21 + 2) × 3 vs 21 + (2 × 3), and contrastive emphases placed on different words in a sentence such as “It's 9 8 11 Brooks Drive.” The data were obtained by the computer controlled x‐ray microbeam system at the University of Tokyo [Kiritani, Itoh, and Fujimura, Acoust. Soc. Am. 57, 1516–1520 (1975)], and pertain, in this paper, to the vertical position of a metal pellet placed on the tongue blade.
