The article studies oratorical speech as a complex linguocultural phenomenon integrating structural, prosodic, and cognitive-pragmatic levels of organization. The aim is to identify the tempo-intonational patterns of public speech that determine its persuasive impact on the audience. The methodology combines acoustic, rhetorical-discursive, and cognitive analysis based on a corpus of 20 Russian and English political speeches. Parameters such as speech rate, pause duration, fundamental frequency range, and intonational variability were measured using Praat and ELAN software. The results reveal statistically significant differences in prosodic parameters: Russian speech exhibits a wider fundamental frequency range (145–260 Hz for men, 190–320 Hz for women) and greater tempo variability (0.27 compared to 0.19 in English), forming an "emotional-pausal" rhetorical model. English speeches demonstrate a higher average tempo (155 words per minute vs. 138) and a logic-oriented rhythmic organization. The scientific novelty lies in substantiating the concept of the "rhythm of persuasion" as a systemic parameter of oral discourse and clarifying the mechanisms of prosodic equivalence in interpreting. It has been established that the coordination of tempo, intonation, and pausing creates cognitive synchronization between the speaker and the listener, enhancing the rhetorical impact. The practical significance of the study includes applications in rhetorical training, simultaneous interpreter education, and the development of automated speech analysis systems. Further research may involve expanding the corpus with multilingual data and employing neurocognitive monitoring technologies to verify the
