The specificity of Kyrgyz vocalism lies in its greater rationality, functionality, relatively less variability in the realizations of the units of the system, in the absence of nasalization that is not historically or phonetically conditioned by the context, frequency in the languages of the South Siberian region, in consistent flat-slit labialization in the subclass of rounded phonemes. The phonetic processes peculiar to the Kyrgyz language and South Siberian Turkic cannot be interpreted as the result of contact with any one of the languages of the Siberian area - the commonality of the phonetic landscape, apparently, is due in historical retrospect to regional reasons. The theoretical and practical significance of the study. The theoretical provisions and conclusions of the dissertation work can be used  and are already being used - in comparative and typological studies of the phonetics of the Turkic languages, in dialectological and linguistic-geographical developments, when writing phonetic sections in textbooks and textbooks on Kyrgyz, Russian and foreign languages for schools and special educational institutions, when developing lecture courses on Turkic phonetics for linguistic departments of humanities faculties of universities. The clarifications and additions made to the hardware methodology for processing and interpreting data are applicable in the study of sound systems of languages of various families and can be used to obtain important data in the construction of phonetic typology.
