초록
This paper examines the sonorant coda, stop onsets (voiceless unaspirated lenis and voiceless unaspirated fortis) and their following vowels in Korean. This study focuses on five dimensions of the phonetics of two-syllable words with tense, tensified or lax stops for ten female speakers: duration, VOT, CoG, H1-amplitude, and H1- H2. This study reveals that the coda preceding tensified stops is longer than the coda preceding lax stops, and that the H1-amplitude at the coda preceding tensified stop falls sharply at 70% position of coda in contrast to the coda preceding lax stop that shows nonsignificant change in H1-amplitude. It is shown that the H1-amplitude of the vowel following tensification drops more sharply at 70% position than that of the vowel following tense stop at S1. For VOT, tense stops in S1 are longer than the tensified stops in S2, and there is no significant difference between lax and tensified stops in S2. For CoG, tensified stops are higher than lax stops in S2, while lax stops are higher than tense stops in S1. It is concluded that tensified stops in S2 are acoustically different from tense stops in S1.
Abstract
This paper examines the sonorant coda, stop onsets (voiceless unaspirated lenis and voiceless unaspirated fortis) and their following vowels in Korean. This study focuses on five dimensions of the phonetics of two-syllable words with tense, tensified or lax stops for ten female speakers: duration, VOT, CoG, H1-amplitude, and H1- H2. This study reveals that the coda preceding tensified stops is longer than the coda preceding lax stops, and that the H1-amplitude at the coda preceding tensified stop falls sharply at 70% position of coda in contrast to the coda preceding lax stop that shows nonsignificant change in H1-amplitude. It is shown that the H1-amplitude of the vowel following tensification drops more sharply at 70% position than that of the vowel following tense stop at S1. For VOT, tense stops in S1 are longer than the tensified stops in S2, and there is no significant difference between lax and tensified stops in S2. For CoG, tensified stops are higher than lax stops in S2, while lax stops are higher than tense stops in S1. It is concluded that tensified stops in S2 are acoustically different from tense stops in S1.
