This paper is an ultrasound-based articulatory study
of the impact of syllable-position and utterance
position on tongue shape and tongue-gesture
magnitude in liquid consonants in American, Irish
and Scottish English. Mixed effects modelling was
used to analyse variation in normalised tonguegesture magnitude for /r/ and /l/ in syllable-onset and
coda position and in utterance-initial, medial and final
position. Variation between onset and coda mean
midsagittal tongue surfaces was also quantified using
normalised root-mean-square distances, and patterns
of articulatory onset-coda allophony were identified.
Despite the fact that some speakers in all varieties
used tip-up /r/ in syllable-onset position and bunched
/r/ in coda position, RMS distance results show
greater degrees of similarity between onset and coda
/r/ than between onset and coda /l/. Gesture
magnitude was significantly reduced for both /l/ and
/r/ in coda position. Utterance position had a
significant effect on /l/ only.
