    The effects of syllable and utterance position on tongue shape and gestural magnitude in /l/ and /r/
    (International Phonetic Association, 2019-08-10) Lawson, Eleanor; Leplatre, Gregory; Stuart-Smith, Jane; Scobbie, James M.
    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 tongue-gesture 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.

    Viewing speech in action: Speech articulation videos in the public domain that demonstrate the sounds of the International Phonetic Alphabet (IPA)
    (Taylor & Francis, 2016-04-11) Nakai, Satsuki; Beavan, David; Lawson, Eleanor; Leplatre, Gregory; Scobbie, James M.; Stuart-Smith, Jane
    In this article, we introduce recently released, publicly available resources, which allow users to watch videos of hidden articulators (e.g. the tongue) during the production of various types of sounds found in the world's languages. The articulation videos on these resources are linked to a clickable International Phonetic Alphabet chart ([International Phonetic Association. 1999. Handbook of the International Phonetic Association: A Guide to the Use of the International Phonetic Alphabet. Cambridge: Cambridge University Press]), so that the user can study the articulations of different types of speech sounds systematically. We discuss the utility of these resources for teaching the pronunciation of contrastive sounds in a foreign language that are absent in the learner's native language.
