Interference Features in the Russian Speech of a German Native Speaker in Internet Interviews

The native language interference causes multilevel speech errors in the non-mother tonque. This research featured mistakes made by a native German speaker in a Russian online interview to Deutschklasse YouTube vlog. The respondent learned Russian in adulthood and is a certified proficiency speaker (C2). The features of bilingualism and interference were examined through the concepts of modern linguistic and didactic issues of lapsology, or erratology, in virtual environment, which is a relevant area of fundamental and applied linguistics. The methodology included the subjective method, the method of phonetic notation (International Phonetic Alphabet), the method of comparative phonetics, and the glossary method (Leipzig glossing rules), which were applied to grammar, word-formation, and vocabulary. The interviewee made few mistakes (1.05 per minute). These mistakes could be reduced to German-Russian interference. The diaphonic errors (phonetic interference, 0.77 per minute) did not hinder the understanding, and neither did the diamorphic errors (grammatical interference, 0.22 per minute). There were only three dialectical errors (lexical and word-formation interference, 0.03 per minute) that hindered the understanding to a minor extent. The research results had a fundamental, applied, and didactic relevance.
