The amount and scope of phrase-final lengthening in Korean

Jiyoung Jang, Argyro Katsika


Phrase-final lengthening is a well-established phenomenon. However, what determines the amount and scope of the effect is still unclear. Previous studies have reported prominence as a key factor, but these findings rely on data from stress languages. Here, we use electromagnetic articulography to examine the amount and scope of phrase-final lengthening in Korean, a language with no lexical-level prominence, as a function of factors that are associated with prominence, i.e., focus position and accentual phrase (AP) length. Stimuli sentences included the test words either in phrase-final or phrase-medial positions with focus position (initial AP, final AP) and final AP’s length (long, short) manipulated. Formation and release durations of their consonant gestures were calculated. Phrase-final lengthening affects the final syllable, with greater amount of lengthening found on its coda as opposed to its onset, suggesting that lengthening is progressive, i.e., decreasing with distance from the boundary. Neither focus position nor AP length affect the scope of lengthening, but AP length affects the amount of lengthening of the final coda consonant. Finally, boundary-related shortening is detected prior to the lengthening effect, and is presumably anticipatory in nature. The implications of these results for prosodic structure, prosodic typology and speech planning are discussed.
