The majority of the previous studies on tone realization in South Kyungsang Korean are concerned with the vertical domain of fundamental frequency (F0 henceforth) values (in Hz or in semitones), little is known about F0 realization on the temporal domain. The present study examines paralinguistic factors affecting tonal realization on the temporal domain of South Kyungsang Korean. In the study, we compare F0 peak delay patterns across the genders of the speakers and the word types (English loanword and native words in South Kyungsang Korean). Forty eight young South Kyungsang native speakers were presented with virtual listeners and recorded twelve trisyllabic words composed of two categories of loanwords and native words. Normalized F0 peak delay was the focus of the investigation along with segmental landmarks. The statistical results revealed the different F0 delay patterns between native words and loanwords, and between female and male speakers. Loanwords and female speakers showed relatively more F0 peak than native words and male speakers respectively. This finding indicate paralinguistic factors such as genders and the word types affect tonal realization on the temporal domain.
