In the research the Ukrainian phonetic terminology is represented as a complex system of one-word terms and terminological phrases. It has been developed during the ХХ century and the first decades of the ХХІ century as linguists-theoreticians and researchers-experimentalists has been shown attention to the problems of the language sound construction and peculiarities of its functional modification. In the dissertation the stages of the development of the Ukrainian phonetic terminology are constituted and their peculiarities are determined. The tendency of creating new terms on the national base, internal lexical, grammar and orthographical resources is correlated at the beginning of the XX century - thirties of the XX century. The following the 40-50 of the XX c. are connected both following the traditions of Moscow and Leningrad phonetic schools and appropriate terminology and widening the range of the directions of researches (historical phonology, dialect phonology, experimental contrast phonetic researches), argumentation of fundamental theoretical and practical issue of the phonetics methodology - the meaning of the term "phonema". It is mentioned that the codification of definitions of linguistics in "Dictionary of linguistic terms" by Y.Krotevich and N.Rodzevych became the point of systematization of accumulated experience and precondition for the wide standards establishment of Ukrainian phonetic terminology during the third stage (60-70 XX c.). According to the last it was discovered some variance, debatableness, unestableshment of some terms, systematizations consonants and vowels of the Ukrainian language. In this period the tendency of maximum approach to the international research standards in the field of phonetics was increased. The period of the 80 XX c. is characterized by the processes of forcing out of the terms variants that were not unsupported by the following researches as well as correlation the terminological meaning of the definitions of phonetics and phonology with Russian phonetic schools achievements. The modern period is important for the development of phonetic terminology because of standardization and codification in different forms. To characterize Kharkiv, Kyiv and Odessa phonetic schools the territorial criteria connected with such factor as "scientific problem, theoretical and practical work of researcher-phonetist" was proposed. The connection of standardization of terminological apparatus of the language history, dialectology, grammar, stylistics, orthoepy to subsystem of phonetic terms is taken into consideration. According to the results of the research was found out the fact that the phonetic terminological system levelling took place on the background of the following tendencies: 1) constitution of international standards of term usage under the influence of conclusions and recommendations to unification appropriate term system accepted by International terminological committee on linguistics (1960 - 1977); 2) intensification of the process of grammar and orthographical standards of the Ukrainian language leveling under the influence of the Russian language practice causing the loss of the tendency of creating own term-units according to the internal laws of the Ukrainian language; 3) further saving (from the 70 XX c. till nowadays) the tradition of parallel using of international term-units and their analogies, standardized in the field of phonetics in the middle of the XX c.; 4) researchers aspiration for applying in their works so called "individual terms" displaying the results of advanced studying of some phenomena; 5) from the middle of the 50 XX c. when the principal terminological groups of the Ukrainian phonetic terminology was established (28 essential unities) the development of the Ukrainian phonetic terminology is connected on the widening of the distribution of the key terms inside the groups, changes in syntagmatic of phonetic terms causing the quantitative increase of components; 6) predominance of quantitative changes in the Ukrainian phonetic terminology over qualitative ones from the 60 XX c. as at that time the standards of word formation, grammar designing of the language units such as terminological ones were established. The increase of term formation in the field of phonetics on the basis of the terminological phrases shows the tendency of speech saving efforts, development and augmentation of prepositive components-adjectives and tendency to contribution of easier adoption of new terms and definitions; 7) archaization of some terms in relation to further specification of the sound phenomena classification. It is found out that the main way of creation of phonetic one-word terms is morphological (affixal, stemcomposition, wordcomposition) widespread in the 20-60 XX c. As the fact that the Ukrainian phonetic terminology was formed on the base of the terms and definitions of the foreign origin and the proper Ukrainian, East Slavonic, lexical and semantic resource, so the principal terms are used as ready-made terms with such structural peculiarities, which are not new. Hierarchical subsystem of the Ukrainian phonetic terminology is linked by hyper-hyponimic correlations in classes and subclasses of theme unities of the terms under research; the relations of the oppositional correlation, synonimy, sporadically - homonymy, polysemy are followed, the phenomena of structure and grammar and morphological variance are saved. In conclusion it should be mentioned the fact that the Ukrainian phonetic terminology has been established and developed during the century that is represented by the codification of sources - textbooks, dictionaries, monographies on different stages of the history of linguistics.
