Yashnyk O. Acoustic principles of development of Ukrainian-speaking diagnostic articulation tables

The dissertation work is dedicated to the research of existing diagnostic materials in the Ukrainian language for conducting speech audiometry in order to check the condition of the human auditory system, and to the comparison with the balanced diagnostic tables in Russian. The relevance of the work lies in determining the objective criteria for the selection of language material, as such diagnostic material fully reflects the linguistic and phonetic features of the studied language. The creation of diagnostic material in the Ukrainian language for hearing testing is an urgent problem, particularly for children of primary school age, as today there are no regulations that are able to certify their existence. The high difficulty lies in the lack of an averaged spectrum of Ukrainian as an objective indicator for the selection of material. Thus, the development of new and improvement of existing methods of selection of language material and the creation of articulatory diagnostic tables is an urgent scientific and technical task of psychoacoustics. The author generalizes and substantiates the solution of the scientific problem, which lies in improving the existing way of finding the average spectrum of the language, as well as its definition for the Ukrainian language. The averaged spectrum for the Ukrainian language, obtained in an experimental way, is compared with a similar characteristic of a number of other European languages and language groups. This makes it possible to create language diagnostic material for articulation tables, taking into account the peculiarities of statistical characteristics inherent in the Ukrainian language. The dissertation consists of: introduction, 4 sections with conclusions for each of them, general conclusions, a list of the used sources and appendices. The full volume of the dissertation is 142 pages of printed text, including 38 pictures. The size of the main part of the dissertation is 116 pages. The appendices are presented on 26 pages. The list of used sources includes 69 items. The object of the research is the process of determining the spectrum of the Ukrainian language and a number of requirements needed for the creation of language material of diagnostic articulation tables for speech audiometry. The subject of the study is the generalized criteria that must be met by balanced diagnostic articulation tables.
