(on MRI data)
The paper aims to describe the articulatory traits of the Baraba-Tatar phoneme o /ʊ̇ / by the
somatic methods. The method used is magnetic resonance imaging (MRI). Eighteen Barabian
tomograms comprising o-type articulation have been described and analyzed according to the
technique adopted in the V. M. Nadelyayev’s Laboratory of Experimental-Phonetic Researches (Institute of Philology SB RAS). The text provides only general observations and conclu-
sions, with a full description of all tomograms given in three tables. The experimental-
phonetic analysis of the Baraba-Tatar tomograms of the vowel o allowed the author to draw
several conclusions. There is a variability of the o-type tunings in Barabian, the most typical being the central-back narrow labialized ejective realization. Though it is very narrow and is
phonetically transcribed as /ʊ̇ /, it is acoustically perceived as o. While producing the sound o,
the oral and pharyngeal cavities become very small, producing the effect of tension. Additional narrowing occurs between the soft palate and the tongue back as well as between the
upper teeth and the lower lip, thus preventing the airflow from free release. The lip position is
also unusual: instead of protruding forward, the upper lip moves back, tightly covering the
upper teeth to produce an interesting acoustic effect. To sum up, further investigation of all
vocal system units of Baraba-Tatar is needed to draw ultimate conclusions about the typologi-
cal belonging of the language under consideration.
