Аннотация: The research in question is aimed at the experimental MRI-investigation of articulatory gestures corresponding to Russian bilabial non-palatalized phonemes [b] and [m]. Being estimated as the prominent type of velarized consonants in Russian, these phonemes have been taken as target group in a series of MRI experiments to study palatalisation – velarisation relationship in the Russian phonetic system. An experimental dataset was based upon 2D MR-images, audio- and video recordings taken from 2 native speakers of Russian (male and female) producing VCCV sequences (Russian pseudo-words with the second vowel stressed) containing labial consonants in the vocalic contexts [a]_[a], [a]_[e]. The original experimental method of MRI investigation relied on gated and time-related MR-scanning of numerous repetitions of the same speech sequence for further reconstruction of articulatory movement(s) progressing in time being plotted from MR-images across several repetitions within a session. Experimental data present a considerable grade of image matching for both labial consonants, either nasal or non-nasal, in the [a]_[a] frameset (except soft palate configuration in nasals). However, we revealed distinct differences in tongue position and form of the tongue blade on articulatory contours taken from MR-images of sectional sagittal view of the mouth cavity for the labial phonemes under investigation placed in the [a]_[e] frameset. In this context the main difference between nasal and non-nasal labial consonants’ articulations seems to be determined not only by the specific configuration and position of the soft palate (velum), but by the conflicting articulations of consonant’s velarisation requirements on the one part, and anticipatory look-ahead coarticulation to the mid-high centralized vowel [e], on the other. We suppose the observed differences being the main reason for several phonotactical constraints observed in the modern Russian language pronunciation practice. Thus, Russian standard pronunciation dictionaries contain only very few words (mainly adopted from other languages) with the hard labial nasal consonant [m] or bi-labial stop consonant [b] preceding vowel [e] in a root or within the single syllable.
