Abstract.
This paper investigates the acoustic and prosodic-structural features of Russian vowels in South Russian and Moscow phonetic variants. The aim of the study is to identify key features that distinguish South Russian and Moscow phonetic variants using machine learning methods. The research, based on the reading of neutral phrases by native speakers from Moscow, Moscow Oblast, and Southern Russia, involved a comprehensive analysis of speech data: annotation, acoustic measurements, construction of a logistic regression model, and assessment of feature permutation importance. Scientific novelty lies in the quantitative assessment of the contribution of various speech parameters – temporal, spectral, and structural – to the task of binary classification of regional pronunciation variants. The study revealed that the main differentiating feature is the temporal characteristics of vowels: absolute duration is significantly associated with the Moscow variant, whereas the relative duration of the vowel within the segment structure is associated with the South Russian variant. Spectral parameters demonstrated minimal differentiating potential.
