Abstract: Simultaneous interpreting (SI) is one of the most complex types of cognitive and communicative activity. Such factors as the simultaneity of speech perception and speech production, multichannel nature of data received for processing, high speed of interpreting, etc. dictate the need educate highly qualified interpreters. This also indicates the importance of determining the criteria that must be taken into account while selecting speeches for the step-by-step mastering of the technique of SI. The subject of the study of this article are the factors influencing the handling of information in the process of simultaneous interpreting and embodied in the individual syntactic features of the speaker's speech. These features determine speeches' translatability and can either represent some destabilizing factors for simultaneous interpreters, or contribute to a more accurate and high-quality interpreting. The author analyzes the syntactic features inherent in the speeches delivered by two presidents of the French Republic – N. Sarkozy and F. Hollande. The article provides a comparative analysis of written texts and delivered speeches and a linguistic analysis of the text in order to identify syntactic features and to describe the impact they can have on the work of interpreters. The author of the article came to the conclusion that the analysis of such features can help in the selection of authentic speeches at the initial stage of mastering the technique of SI and for practicing and automating certain skills at a more advanced level or in the selection of speeches for intensive training in the language combination "French – Russian". The results of the research can be used in the study of texts produced by other speakers and / or in other languages. The results of the research can find application in educational and pedagogical activities, as well as in real interpreting practice.
