Аннотация:Paper presents main results of a targeted MRIinvestigation
of articulatory patterns of the Russian
diphthongised (gliding) vowel phonemes, vowel /ɨ/
first and foremost. The investigation‟s relevance is
assured by serious general discordance of opinions
discussing articulatory patterns of diphthongised
Russian vowel /ɨ/. Our research revealed critical
differences in the vowel‟s articulatory dynamic
patterns caused by specific role of core articulators
in formation of heterogeneity of a speech sound. The
first articulatory pattern supports gliding articulation
of the vowel /ɨ/ through gradual displacement of
tongue root and tongue blade/tongue dorsum
towards anterior area of the buccal cavity, the other
articulatory pattern is spatially and temporary
realized through complex interaction of both tongue
transformations and a special mandible articulatory
gesture. Such exceptional jaw activity being
unknown in common descriptions of the Russian
articulatory base would make Russian vowel /ɨ/ a
singular item within phonetic system of the Russian
language.
