The relevance of the study lies in the fact that today one of the problems of linguistics is the comparative study of languages. Comparative study of unrelated languages makes it possible to identify features of linguistic phenomena that are barely noticeable when studying one or another language separately. These features, along with the formation of the image of a typological structure, cover both the entire language and the study of its individual parts. The purpose of the study is to analyze the effectiveness of a comparative study of the phonetic features of the language structures of the Kazakh and English languages. To achieve the research goals, the following methods were used: functional, communicative, and comparative. The starting point of training is the explanation of the role of pronunciation in the overall process of formation and perception of speech. The article emphasizes the importance of the comparative study of languages of different structures in the field of phonetics. It is described that the sounds of the language are not pronounced separately, but are used in combination with each other within a word or between words and mutually sequentially. The results of the work determined that both in Kazakh and English, sounds in the composition of words or between them influence each other and are pronounced consonantly, and questions of sound extraction play an important role in teaching speaking skills, as well as in other types of language communication. It seems necessary to enrich the repertoire of techniques used in phonetic didactics by popularizing comparative methods. Given that knowledge of the elements of phonetics is an integral part of language learning, the practical significance lies in the fact that the study can be essential in the process of preparing a productive comparative study of the English and Kazakh languages in the context of phonetics.
