Production-ready Bulgarian to Ukrainian translation API

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

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

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

Real-time Bulgarian to Ukrainian translation

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

Yes. Soniox streams Ukrainian while Bulgarian is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.

That direction is supported too. See the Ukrainian to Bulgarian page, or use two-way translation to run both directions in one session.
Does Soniox handle Bulgarian dialects and accents?
Yes. Soniox handles Bulgarian dialects like Eastern Bulgarian and Western Bulgarian in a single model, so Ukrainian translation stays accurate across regions.
Which other providers support Bulgarian to Ukrainian?

How fast is Bulgarian to Ukrainian translation?
Soniox streams Ukrainian as Bulgarian is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
