Abstract
The three-way laryngeal distinction among voiceless Korean stops has been well
documented for the Seoul dialect. The present study compares the acoustic and aerodynamic
properties of this stop series between two dialects, non-tonal Seoul and tonal South
Kyungsang Korean. Sixteen male Korean speakers (eight from Seoul and eight from
Kyungsang) participated. Measures collected included VOT, f0 at vowel onset, H1-H2,
and air pressure and airflow. The presence versus absence of lexical pitch accent affects
both the acoustic and aerodynamic properties. First, Seoul speakers use a combination of f0
and VOT to distinguish the three-way contrast of Korean stops, while Kyungsang speakers
mainly use VOT. Second, the presence of lexical pitch for Kyungsang speakers makes f0
an unreliable acoustic cue for the three Korean stops. Third, dialectal differences in VOT to
mark the three-way distinction support the notion of a diachronic transition whereby VOT
differences between the lenis and aspirated stops in Seoul Korean have been decreasing
over the past 50 years. Finally, the aerodynamic results make it possible to postulate the
articulatory state of the glottis, indicating a positive correlation with acoustic parameters.
Based on the acoustic and aerodynamic results, phonological representations of Korean
stops for the tonal and non-tonal dialects are suggested.
