Post-velar ultrasound: The relationship of pharyngeal and laryngeal articulation to phonological contrasts

Jonathan Washington (Swarthmore)
Yana Outkin (Swarthmore)
Steven Lulich (Indiana University)

Description:  This workshop examines the relationship between post-velar articulations—such as pharyngeal and laryngeal—and phonological contrasts as studied using ultrasound imaging. Recent work, for example, has found the position of the tongue root to correlate with features such as vowel anteriority, palatalisation, and voicing. While physiological and cognitive mechanisms have been devised to explain these correlations, none of this has found its way into general models of speech production. This workshop will include talks on case studies, posters on methodology, and a period for discussing the broader topic to open new ways of thinking and avenues for conducting relevant research.

Thursday, June 25, 1pm - 4:30pm
