Studying the structure of the sound of Russian speech by Chinese and Ghanaian students in a digital format: a linguodidactic aspect

The purpose of the research is to study the peculiarities of the structure of the sound of Russian speech by Chinese and Ghanaian students at different levels of study, based on experimental phonetic programs. The subject of the study is the intonational structure of the main communicative intentions: greeting, address, completion, incompletion, a question without an interrogative word, a question with the Russian conjunction «а» (“and”), a positive evaluation and surprise. The study contributes to the creation of an ethno-oriented methodology for teaching Russian intonation. The scientific novelty is in the analysis of the sound of the Russian speech of foreign students at the syntagma level in comparison with that of a native Russian speaker using the Praat and Lingvodoc programs. The results of the study consist in the visual representation of the peculiarities of the structure of the main communicative intentions in the Russian speech of Chinese and Ghanaians to predict and correct errors at the level of intonation.
