In: Proceedings of the 18th International Congress of Phonetic Sciences (ICPhS), Glasgow, 10-14 August 2015, [Paper no: 332].97808526194140241-0669https://www.internationalphoneticassociation.org/icphs-proceedings/ICPhS2015/Papers/ICPHS0332.pdfhttps://eresearch.qmu.ac.uk/handle/20.500.12289/3941We investigate the contribution that lingual gesture delay makes to lenition of postvocalic /r/. This study uses a socially-stratified, audio-ultrasound corpus of Scottish English containing recordings from two sociolects; one with postvocalic /r/ weakening and the other with strengthening. We quantify auditory strength of rhoticity and the timing of the anterior lingual gesture relative to the offset of voicing in CVr words: bar, bore, fur, or onset of a following consonant in CVrC words: farm, herb, burp, in order to show that there is a statistically significant correlation between weak rhoticity and a late articulatory gesture. Our ultrasound data also show that during the process of final consonant vocalization/deletion, underlying articulatory gestures may persist.http://creativecommons.org/licenses/by-nc-nd/3.0/deed.enRhoticityUltrasoundSociophoneticsSound ChangeIntergestural Timingarticle
