Temporal and spectral characteristics of the intervocalic consonant clusters in Korean

Abstract

Park(2008) showed that there is no significant difference in specific segment duration and their temporal structure between VCC[Asp]V and VC[Asp]V, and between VCC[For]V and VCC[Len]V and VC[For]V, where V stands for vowel, C for consonant, [Asp] for aspirated, [For] for fortis, and [Len] for lenis. He also showed that there is no significant difference in consonant duration between a singleton and a geminate when the following C is [For] or [Asp], but a significant difference between them when the following C is [Len]. On the other hand, Park(2005) showed that there is a significant difference in phonation type index k (PTI k) across phonation types, where PTI k presents a single and simplified measure of the spectral tilt, which is free from the effects of fundamental frequency and vowel quality. This study, by applying Park(2008)’s and Park(2005)’s methods, investigates temporal and spectral characteristics of the consonant clusters of the other manners and places of articulation. The results showed that temporal characteristics present a similar pattern to those of Park(2008), and that spectral characteristics are associated with the phonation identity of the final consonant of the intervocalic consonant clusters.
