Production-ready Ukrainian to French translation API

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

Ukrainian (Indo-European > Slavic > East Slavic) and French (Indo-European > Romance > Western Romance) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Ukrainian is written in Cyrillic and French in Latin, so Soniox emits correctly scripted French text.

Real-time Ukrainian to French translation

Soniox streams the Ukrainian transcript and the French translation on the same connection, word by word, so meaning lands while the speaker is still talking.

Frequently asked questions

How do I translate Ukrainian to French with the API?
Add a translation block to your real-time request with source_language "uk" and target_language "fr". Soniox transcribes Ukrainian and streams the French translation over the same WebSocket.
Is Ukrainian to French translation real-time?
Yes. Soniox streams French while Ukrainian is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating French to Ukrainian?
That direction is supported too. See the French to Ukrainian page, or use two-way translation to run both directions in one session.
Does Soniox handle Cyrillic to Latin output?
Yes. Soniox outputs correctly scripted French text in Latin directly in the token stream.
Does Soniox handle Ukrainian dialects and accents?
Yes. Soniox handles Ukrainian dialects like Northern Ukrainian, Southeastern Ukrainian, and Southwestern Ukrainian in a single model, so French translation stays accurate across regions.
Which other providers support Ukrainian to French?
Based on their public docs, OpenAI, Azure, and Speechmatics list both Ukrainian and French for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Ukrainian to French translation?
Soniox streams French as Ukrainian is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
