This article provides a contrastive and typological analysis of phonetic level units in the English and Uzbek languages. The study is based on phoneme theory, vowel and consonant systems, phonotactic patterns, and suprasegmental features. In English, vowel oppositions are numerous, diphthongs are present, vowel length has phonological significance, and a free stress system plays an important role in distinguishing meaning at both word and sentence levels. In contrast, the Uzbek language demonstrates phonotactic regularity, agglutinative morphology, and a relatively stable stress pattern, while pronunciation is generally more systematic and simplified.
