Russian contrasts plain and palatalized consonants, but this contrast is commonly reported to be neutralized before a palatal glide, where plain consonants undergo assimilatory palatalization. Recent articulatory evidence, however, suggests that underlying and assimilatory palatalization may be phonologically neutralized, but it is phonetically incomplete. This study investigates the internal gestural organization that gives rise to such incomplete neutralization in Russian. Building on the empirical findings of previous work, the current study employs articulatory modeling to examine how different gestural coordination can generate subtle differences between the two palatalization types. We created four gestural models using Task Dynamic Application (TADA). Each model varied in the presence or absence of velar gestures and in the coordination relations among labial, palatal, and velar articulatory gestures. Simulation outputs were directly compared with temporal and spatial measures reported in previous work. The model that best accounted for the empirical data posits eccentric-phase coordination between velar and palatal gestures in assimilatory palatalization, combined with in-phase coupling between labial and palatal gestures. This model successfully replicated the empirical findings: complex-segment timing for both conditions as well as greater tongue body retraction at palatal gesture onset and longer onset-to-onset lags in assimilatory palatalization. The current study explicitly shows the internal gestural organization that can account for incomplete neutralization between underlying and assimilatory palatalization in Russian.
