Trusted by teams building global voice products

Production-ready Ukrainian to Russian translation API

Real Ukrainian speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Russian while the speaker is still talking.

Ukrainian and Russian both belong to the Indo-European > Slavic > East Slavic family, so cognates and shared structure carry over cleanly into the translated Russian output.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

That direction is supported too. See the Russian to Ukrainian page, or use two-way translation to run both directions in one session.
Ukrainian and Russian are both Indo-European > Slavic > East Slavic — does that affect quality?
Shared family structure and cognates generally help. Soniox uses the same model for every pair, so quality stays consistent whether the languages are closely related or not.

Yes. Soniox handles Ukrainian dialects like Northern Ukrainian, Southeastern Ukrainian, and Southwestern Ukrainian in a single model, so Russian translation stays accurate across regions.
Which other providers support Ukrainian to Russian?
