ABSTRACT

Purpose:
The purpose of this study was to measure durations of Korean vowels.
Method:
Using a speech-recording program, 20 normal-hearing participants recorded 20 Korean vowels. Each vowel was recorded five times and the second, third, and fourth recorded vowel durations were used for analysis of durations.
Results:
On average, vowel durations for female speakers were longer than the durations for male speakers. Specifically, 11 vowel durations for female speakers were significantly longer than the durations for male speakers and the other nine vowel durations for female speakers were not. In addition, across-vowel differences in duration were evident not only for male speakers but also for female speakers. Generally, durations of diphthongs were longer than durations of monophthongs.
Conclusion:
The results of this study provide information about effects of gender and vowels in vowel durations. Vowel durations may be one factor to discriminate vowels.
