SUMMARY
Speech discourse is the communication between people, that is, the speaker seeks to influence the recipient in a conversation, using deep thoughts and meaningful words, expecting to receive a response from the addressee. In modern Kazakh linguistics, speech discourse is being explored in various ways as a reflection of people's relationships and actions. This research aims to study intonation of the text in the form of official radio interview and to reveal pragmalinguistic peculiarities of it. We used methods of audit, experimental and electro-acoustic analysis for this research. In the article, speech discourse is analyzed pragmalinguistically and its intonation features are investigated by experimental research. Consequently, we took unprepared speech for experimental research, where the participant of interview was informed about the topic of the conversation. However, despite the fact that the theme of the issue was given, the discourse in the form of a previously unprepared radio interview is provided as the subject of research. Among other findings, the results of the study showed that it is advisable to use appropriate pauses, especially the pauses of hesitation, while speaking.
