    Abstract

    Articulatory coordination in English phonemic vowel length contrasts has not been systematically explored. Australian English (AusE), which has a true phonemic vowel length contrast in the open vowels /ɐː-ɐ/ (as in tart-tut), provides a natural control case for exploring articulatory vowel length. Intergestural coordination was examined using Electromagnetic Articulography in stop-initial syllables differing in vowel length produced by five speakers of Australian English. Constriction formation of the supraglottal consonant gesture in the onset was synchronous with the nuclear vowel gesture irrespective of vowel length. Constriction release of the onset consonant was delayed, and VOT lengthened, in syllables containing a phonemically long vowel (tart), compared to syllables with short vowels of the same quality (tut). The findings are consistent with a model of syllable structure in which there is independent control of constriction formation and constriction release in onset gestures.
