The most effective way to understand the historical development of languages, changes in vocabulary, and linguistic structures is through dialect studies. Dialects provide a rich source for tracking regional differences in the phonetic structure of a language and transformations throughout its historical processes. In this context, dialect research holds great importance, particularly in the analysis of phonetic phenomena. These phenomena help trace changes in a language's phonetic structure, helping us understand how it evolved from the past to the present. Turkish, with its extensive geographical spread and historical diversity, provides a wealth of data for dialect research. Kazakh dialects spoken in the southern region of Kazakhstan are an important area of study in this context. The main goal of this study is to thoroughly examine the phonetic phenomena observed in these dialects. For this purpose, a study was conducted in 26 villages including Teke, Karnak, Karaşık, Savran, Kandöz, Şornak, Sultanbek Kojanov, Şiyeli, Kojakent, Özgent, Tügisken, Talap, Tömenarık, Beşarık, Kelintöbe, Köktöbe, Janaarık, Manap, Akjol, Ekpindi, Sunakata, Karatöbe, Maylıtogay, Tasböget, Otrar, Baltaköl. An attempt was made to reveal the differences between these dialects and Standard Kazakh Turkish, especially based on features such as the use of vowels, length, roundness, and width. For example, although there is no rounding phenomenon in Standard Kazakh Turkish, the sounds that follow are also rounded in the regional dialect due to the effect of the rounded vowel in the first syllable: jürüwgö ˂ jurwge “to walk”, ülkön ˂ ülken “big”, üydö ˂ üyde “at home”. This examination aims not only to identify regional differences but also to assess the historical ties and geographic influences on the language. It is expected that the findings could offer a broader perspective on the phonetic structure of the Kazakh language and contribute to future comparative Turkishology studies. It is anticipated that the analysis of phonetic phenomena could lay a foundation for creating dialect atlases and understanding relationships between dialects.
