This article compares the phonological system of the Uzbek language with the phonological systems of other Turkic languages, in particular Kazakh, Kyrgyz, Turkmen and Turkish, and analyzes their similarities and differences. The study studies the system of vowels and consonants, the number of phonemes, the stress system, and phonological processes (assimilation, dissimilation, elision, etc.).

The Uzbek language is an agglutinative language and has a very rich phonological system. However, it has its own characteristics compared to other Turkic languages. For example, some consonants (g’, o’, q) are used more actively in the Uzbek language, while in some Turkic languages ​​these sounds are used less often or do not exist at all.

According to the results of the study, it is determined that the phonological differences between Turkic languages ​​are associated with historical development, contact with other languages, migration processes, and dialectal changes. The article serves to determine the degree of phonetic similarity of Turkic languages ​​through a comparative-linguistic analysis of phonological systems.

The article serves as a useful theoretical and practical resource for linguists, philologists, and researchers involved in phonology. It can also serve as a basis for determining the uniqueness of the phonological system of the Uzbek language.
