Summary: Urgency. Ukrainian is the state language and mother tongue of our people. One of the important components of language is intonation. It conveys the meaning of speech, expresses the attitude of the speaker to what is said, and provides emotional expression values play an important role in speech and at the same time is less explored. Research conducted intonation philologists, linguists. They describe its characteristics and types, such as ascending or descending intonation, but from a technical point of view, these descriptions are no specifics, so it is important to study the characteristics of the speech signal tone and their descriptions to provide measurement capabilities. The purpose and objectives of research. The aim of this work is to study the characteristics of the speech signal tone, methods of analysis of these characteristics and their description of this method to provide design values with which you can be granted a more accurate description of intonation. Object is Ukrainian intonation of speech that is written in the speech signal. The subject of the study is the frequency of the fundamental tone of the speech signal, spectrogram and its intensity. Methods. We study the characteristics of the speech signal, frequency spectrogram basic tone and speech signals. Study occur when changing the tone, its types: smooth, interrogative and such that speech gives a negative value. Its parameters: frequency of basic tone, spectrogram, intensity. Scientific novelty of the results of the master’s thesis is as follows: 1. The dependence of the fundamental tone frequency, intensity and spectrogram signal related to the Ukrainian intonation of speech. 2. Made mathematical calculation frequency change basic tone signal. The practical significance. Mathematical calculation frequency change basic tone will more accurately describe the speech signals when examined intonation to help better understand the dependence of the frequency of the fundamental tone of tone and intonation better establish links with such characteristics as spectrogram and signal intensity. The structure of the thesis. The thesis consists of an introduction, three chapters, the last of which includes conclusions on the study, list of sources. The total volume of 90 pages.
