An Acoustic Analysis of English Monophthong Vowels Produced by Young Adults Using Praat
Abstract
This study analyses the acoustic characteristics of English monophthong vowels produced by young adults using Praat software. The analysis focuses on the first formant (F1) and second formant (F2) frequencies to identify variations in vowel production. This study uses a descriptive approach involving audio recordings of three young adult speakers and one native speaker who pronounce ten selected English words. The recordings are examined using Praat to identify vowel segments and measure their F1 and F2 values in Hertz (Hz). This research was carried by qualitative method. The results show variations in formant frequencies across speakers and words. The findings indicate that vowel production varies according to the speaker and the phonetic environment. The study also demonstrates that Praat is a useful tool for examining vowel characteristics through acoustic measurements. These findings may contribute to a better understanding of English vowel production and support pronunciation learning among English learners.
