Research deals with experimental investigation of efficacy of various acoustic metrics for description of speech rhythm in Russian. Oral task method was used to analyze syllabification behavior of ten native Russian speakers. While Russian language traditionally classified according to its rhythmic templates as stress-timed language, therefore rhythm metrics based on syllable durations, effective for syllable-timed languages, fails to predict regularities in temporal organization of the Russian speech. Thus, various rhythm metrics were applied to experimental dataset to capture stability in temporal parameters of produced speech, e.g. ΔS, ΔV and VarcoV. Our research supported hypothesis that the most relevant parameter of rhythmic organization of the Russian speech is based not on syllabic durations but on intervocalic interval durations (inter-stressed vowels temporal periods), and the most significant rhythm metrics for stress-timed languages is normalized standard deviation of intervocalic interval duration VarcoV.
