The main methods and techniques used are: the method of scientific description and stylistic and contextual analysis. The techniques used in the final part of the speech were singled out, their quantitative analysis was carried out: 1) invitation of the listener to the course, 2) appeal to the goal of the listener or the goal of the online course, 3) appeal to quotations, 4) generalizing conclusion, 5) humorous ending, 6) advice for listeners, 7) containing a call to action, 8) farewell.
