DYNAMICS OF THE TONGUE CONTOUR IN THE PRODUCTION OF GUTTURAL CONSONANTS IN LEVANTINE ARABIC
Résumé
This paper presents a dynamic account of the tongue contour imaged with Ultrasound Tongue Imaging (UTI) and quantified via Generalised Additive Mixed Models, during the articulation of guttural consonants (uvular, pharyngealised, pharyngeal) in Levantine Arabic. Gutturals are claimed to form a natural class and we aim to quantify the degree of (dis)similarity between the members of this class. UTI data were obtained from 8 participants (4 females), producing a variety of consonants (21) in the medial position of a disyllabic frame, with symmetric vowels /iː aː uː/. When compared to plain coronal consonants, and through a dynamic analysis of tongue contours throughout the VCV sequence, the three members of the guttural class show similarities in overall tongue changes towards the front, dorsum, back and root across the three vowel contexts, providing articulatory evidence for the legitimacy of gutturals as a natural class.
