Acoustic Parameters of Vietnamese Word-Initial Consonants: An Analysis of Duration, Intensity, and Fundamental Frequency

Abstract

This study investigates three basic acoustic parameters of 22 initial consonants in Vietnamese, including duration, intensity, and fundamental frequency (F₀). The results show that each consonant group (stops, fricatives, nasals, and laterals) exhibits distinct acoustic properties, with significant differences observed between male and female speakers. These findings help clarify the relationship between acoustic features and articulatory mechanisms in Vietnamese and provide valuable reference data for research in speech processing, speaker recognition, and the development of speech audiometry word lists.
