The role of anterior lingual gesture delay in coda /r/ lenition: An ultrasound tongue imaging study
نویسندگان
چکیده
We 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.

The link between anterior lingual gesture delay and loss of coda /r/: an ultrasound study
It has long been recognised that consonants sound different and have different diachronic sound-change trajectories depending on their location within the syllable (Trager 1959). Articulatory phonetics has sought to discover why liquid consonants in syllable-coda position have a tendency to lenite or be lost over time. The possibility that a delayed anterior lingual gesture in coda liquid conso...
متن کاملTowards an articulatory characterization of european portuguese /l/
Based on EMA data, this study investigates timing and magnitude properties of lingual gestures involved in the production of European Portuguese /l/ in onset and coda positions. Syllable position effects were found: coordination pattern for syllable-initial /l/ is distinct from those observed for syllable-final /l/; the tongue dorsum is more retracted in the syllable-final /l/; /l/s in coda sho...
متن کاملLight and electron microscopic study of the tongue in the White-eared bulbul (Pycnonotus leucotis)
The aim of the present study was to investigate the light and electron microscopic structure of the tongue in White-eared bulbul (Pycnonotus leucotis). Six adult White-eared bulbul (3 males and 3 females) in Shahrekord district were used in the investigation. Samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. Results showed that th...
متن کاملA mimicry study of adaptation towards socially-salient tongue shape variants
We know that fine phonetic variation is exploited by speakers to construct and index social identity (Hay and Drager 2007). Sociophonetic work to date has tended to focus on acoustic analysis, e.g. Docherty and Foulkes (1999); however, some aspects of speech production are not readily recoverable from an acoustic analysis. New articulatory analysis techniques, such as ultrasound tongue imaging ...
متن کاملAn EPG+UTI study of Italian /r/
This paper describes a system for the acquisition, real-time synchronization and analysis of acoustic, electropalatographic (EPG) and ultrasonographic (UTI) data. Simultaneous data on linguo-palatal contact and tongue sagittal profiles are captured for rhotic consonants produced by a native speaker of Italian. Three anterior variants of /r/ ([ɾ], [ɹ̝] and [ɹ]) are shown to be realized with an ap...
