Comparisons of articulator movements from one occurrence to another of a word or sentence often show that a CV or VC transition has an invariant movement pattern over some fixed positional range. An earlier experiment showed that token‐to‐token variation within this “iceberg” portion is very small even when differences in constituent phrase structure or placement of focal stress cause considerable variability at the positional extremum for the adjacent consonant constriction or vowel target [Fujimura and Spencer, J. Acoust. Soc. Am. Suppl. 1 74, S117 (1983)]. The present experiment extends the search for such invariant movement patterns to utterances contrasting in lexical stress. Using the same database obtained by the x‐ray microbeam system at the University of Tokyo [Kiritani et al., J. Acoust. Soc. Am. 57, 1516–1520 (1975)] and a similar search procedure, we examined tongue blade and lower lip movements in tokens of minimal pairs such as insight versus incite. Invariant portions were found for virtual... |
