A joint discussion with SoConDi and PhonDi with Jiseung Kim on "Prosodic Accommodation in Seoul Korean Accentual Phrase."

Abstract
The goal of this study is to examine prosodic accommodation, specifically testing accommodation at prosodic boundaries for speakers of Seoul Korean. Sixteen native speakers of Seoul Korean participated in a sentence completion task where they were asked to complete a target sentence after reading (in the baseline condition) or listening to (in the test condition) a context sentence. In both cases, participants completed the sentence by speaking. The auditory context sentences had artificially manipulated prosody. The manipulation lowered the f0 of the phrase-final syllables that were associated with the Accentual Phrase-final rise, which is a characteristic intonational property of Seoul Korean. The f0 values – f0 maximum, minimum, mean, and range – were extracted from the AP-final syllables of the participants’ responses, and were compared between the baseline and test conditions. The results of the linear mixed-effects model analysis on 14 speakers showed evidence of convergence. The results suggest that effects of accommodation may be manifested in the pitch levels associated with a prosodic boundary. Further analysis is needed to separate the accommodation effects from the effect of pitch declination over the course of the experiment.
