Positional changes of the vocal part of the vibrant in consonant clusters in the pre-stressed syllable

The article is devoted to the phonetic realization of the opened phase of the vibrant in Standard Russian. It reports the results of the experiment on the study of velarized trill in binomial consonant clusters. Using the methods of experimental phonetic analysis, it was revealed that the vocal phase of the vibrant can have different realizations: in the position after another consonant the vocal phase of the vibrant is formed more stably than in pre-position to consonant. In addition, the vocal phase has a longer duration and appears more stably in combinations with more sonorous consonants, such as sonorants and voiced fricatives, and vice versa, opened phase has a shorter duration and is observed less often in combinations with less sonorous consonants, such as stops and voicless fricatives. Thus, the duration and frequency of realization of opened phase of the velarized vibrant varies depending on the degree of neighboring consonant’s sonority, proximity to place of articulation, and it’s position relative to vibrant.
