An Acoustic Study of Sundanese Vowel Sounds and Its Implication on the Teaching of English to the Sundanese Speakers

The purpose of this study is to determine the quality of Sundanese vowel sounds. The study attempts to measure the formant frequency, duration, fundamental frequency, and spectrum of the vowels using a sound spectrograph. A comparison is made between the quality of Sundanese and English vowel sounds to see whether this can be used for practical purposes, e.g., for the teaching of English to Sundanese speakers.
