Item The role of anterior lingual gesture delay in coda /r/ lenition: An ultrasound tongue imaging study(International Phonetic Association, 2015-08-15) Lawson, Eleanor; Scobbie, James M.; Stuart-Smith, JaneWe 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.Item The articulatory and acoustic impact of Scottish English /r/ on the preceding vowel-onset(2009) Lilenthal, JanineThis paper demonstrates the use of smoothing spline ANOVA and T tests to analyze whether the influence of syllable final consonants on the preceding vowel differs for articulation and acoustics. The onset of vowels either followed by phrase-final /r/ or by phrase-initial /r/ is compared for two Scottish English speakers. To measure articulatory differences of opposing vowel pairs, smoothing splines of midsagittal tongue shape recorded via ultrasound imaging are compared. For the acoustic data, differences of the first two formant frequencies at the onset are tested. The results confirm that there is no 1:1 mapping between articulation and acoustics.
