This study explored the vowel effect on acoustic perturbation measures in voice quality analysis. For this study, theperturbation parameters (%jitter, %shimmer) and noise parameter (SNR) were measured with 7 Korean vowels (/a/, /ɛ/, /i/,/o/, /u/, /ɯ/, /ʌ/) using CSpeech with 50 Korean normal young adults (24 males and 26 females). A significant vowel effectwas found only in %shimmer and in particular, low-back /a/vowel was significantly different from other vowels in %shimmer. The least perturbation and noise were exhibited on high-back /ɯ/ and /o/ vowel, respectively. Based on tongue height, asignificant higher %shimmer was demonstrated on low vowels than high vowels. In addition, back vowels in tongueadvancement and rounded vowels in lip rounding showed significantly less perturbation and noise. The least variability ofperturbation and noise within individuals was demonstrated on the vowel /i/ in three repeated measures. However, there wasno significant difference among 3 token measures in single session among vowels tested except the vowel /o/. Consequently,the vowel /a/ commonly used in acoustic perturbation measures exhibited higher perturbation and noise whereas higherstability and less variability were demonstrated on the high-back vowel /u/. These results suggested that the Korean high-backvowel /u/ can be more appropriate and reliable for perturbation acoustic measures.
