Phonological Classification and Acoustic Analysis of Vowel Phonemes in the Uzbek Language

This paper investigates the articulatory and acoustic properties of Uzbek vowel and consonant phonemes. Using data from native speaker recordings and analysis via Praat software, we measure formant frequencies (F1, F2, F3) and propose a revised classification of Uzbek phonemes. Particular attention is given to allophonic variation, acoustic correlates of articulation, and phoneme distribution in literary Uzbek. The study supports phonetic modeling for Uzbek TTS and G2P systems.
