Abstract

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.
