Abstract

|
This study investigates the contribution of vocalic information following the release of an initial stop to the identification of the three-way stop contrast (aspirated, lax, and tense) in Korean. Recent studies showed that there is a strong interaction between consonant types and tone. The findings raise questions concerning Korean listeners´ use of tonal (or vocalic FO) variation in differentiation initial tense, lax, and aspirated stops. The above issues are addressed in the present study using a cross-splicing methodology. The overall results show that low vocalic FO provided the most salient information for lax stops; tense and aspirated stop identification depended on a combination of VOT, FO, and H1-H2 characteristics. The perceptual dominance of FO over VOT for lax stops is consistent with the size of the FO difference in utterance-initial position, as well as their prominent role in Korean intonational phonology.
