Trusted by

Production-ready Bulgarian to Belarusian translation API

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

Bulgarian (Indo-European > Slavic > South Slavic) and Belarusian (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.

Bulgarian and Belarusian through a single stream

Turn it on by adding a translation block with source_language: "bg" and target_language: "be". It runs on the same WebSocket and the same model, with no extra round trip.
