A Study about Formant Characteristics of Nasalized Vowels

비성화된 모음의 음형대 특성 연구

The purpose of this paper was to analyze the effects of nasalization on vowels. Ten males and 7 females produced 5 vowels (/a/, /e/, /i/, /o/, /u/) in conditions: normal and nasalized. In this study we compared normal vowels' formant with nasalized vowels' and examined nasal-formant in the nasalized vowels. The results was as follows: First, there was a significant difference between normal vowels and nasalized in terms of F1 and F2. Second, the nasal formants were observed in nasalized vowels more frequently in females than males. Third, N1 appeared to influence F1 of vowels whereas N2 seemed to have an impact on F2 and/or F3.
