Коартикуляция на стыках слов как показатель наличия просодического шва в русском языке
The paper reports some results of the research, aimed at finding out whether regressive and / or progressive voice coarticulation available in clusters of homorganic labiodental consonants /v/ + /v/ in an external sandhi position in Modern Standard Russian may serve as a cue for detecting the location and depth of prosodic breaks. Combinations of labiodental fricatives /v/ + /v/ at the word junctures result in [ff], [vv] or [fv] pronunciation (with the decreasing abundance) in Modern Standard Russian. The percentage ratio of the above mentioned pronunciation types depends on the strength of the prosodic break between two words: • in the position within an intonation group (no prosodic break) [ff] pronunciation appears fairly stable and makes about 70% of the total case number, while the percentage of [fv] pronunciation (corresponding to the absence of the coarticulation) varies in the range of 1% – 11%. • in the position around prosodic break between two words group [fv] pronunciation detected in more then 80% out of the total case number studied.
