Phonetic and phonological imitation of Seoul Korean aspirated stops

Harim Kwon will present results from her dissertation research today. Her presentation will also be practice for a related talk that she will deliver at the Annual Meeting of the LSA in January. The title and abstract follows below.

Phonetic and phonological imitation of Seoul Korean aspirated stops
Korean has a three-way laryngeal contrast for voiceless stops: tense, lax, and aspirated. To maintain the full three-way contrast, contemporary Seoul Korean requires at least two distinct acoustic cues, stop VOT and pitch of the following vowel. In this presentation, I report results from a speech imitation study which investigates how these multiple phonetic cues operate in spontaneous imitation, asking whether the two cues for aspiration exhibit different imitation patterns. The study further examines whether shadowing (i.e., immediate repetition of target words) and delayed imitation exhibits different imitation patterns, motivated by previous findings showing that, for instance, English speakers imitate extended VOTs of voiceless stops both in shadowing (Shockley et al. 2004) and in delayed imitation (Nielsen 2011). Seoul Korean participants were exposed to target aspirated stops with either extended VOTs or post-stop pitch raised, and their baseline, shadowing, and test productions were compared. In shadowing, only the cue manipulated in the target was directly imitated. In test production, participants “imitated” by enhancing both cues regardless of the manipulation they heard. The results suggest that participants are highly sensitive to the independent manipulation of different phonetic cues. However, imitation with immediate targets is not the same process as that without immediate targets. When there is no immediate target to imitate (i.e., test condition), imitation becomes abstract and phonological.
