Previous description of Korean’s three-way voiceless stop contrast notes differentiation in both voice onset time (VOT) and fundamental frequency (f0) on following vowels (Cho et al., 2002; Kang and Han, 2013; Kang, 2014). In a sound-change in-progress, however, VOT for lenis and aspirated stops has merged. The two are now differentiated primarily through f0 differences (Kang and Guion, 2008; Lee et al., 2013; Silva, 2006). North and South Kyungsang (NK and SK) are pitch accent dialects. SK has not undergone the change (Lee and Jongman, 2012): VOT is still a primary cue, potentially because f0 is already used for the pitch accent system (Lee et al., 2013). In NK, meanwhile, VOT for lenis and aspirated stops overlaps more for female than for male speakers, suggesting a possible change-in-progress (Holliday and Kong, 2011). As questions about the robustness of this change remain, we report data from 23 native NK speakers (6 older and 6 younger males; 5 older and 6 younger females). VOT and f0 findings suggest that the new pattern is incipient in NK: Older male talkers show the old pattern, younger female talkers the new pattern, and older female and younger male talkers fall between the two extremes.
