Ukrainian vowel phones in the IPA context

Abstract

Acoustic and articulatory properties of Ukrainian vowels are investigated in this study and a full set of relevant IPA notations are proposed. The notations are shown in the vowel diagram and the table. The results of the earlier acoustic invariant speech analysis based on special software, auditory and spectrum analysis were used and the results are discussed in the context of general and Ukrainian phonetic laws governing language evolution and acoustic properties of non-stressed vowels in relation to their stressed cognates. Such combined approach resulted in a more detailed vowel inventory than proposed heretofore. The findings of this research contribute to better understanding of Ukrainian language and its special features in comparison with other world languages that may have substantial practical use in various phonetic and translation studies, as well as in modern linguistic technologies aimed at artificial intelligence development, machine translation incorporating text-to-speech conversion, automatic speech analysis, recognition and synthesis, and in other areas of applied linguistics.
