Build with API

Serbian to Ukrainian speech translation API

Stream Serbian (Српски) speech and get Ukrainian (Українська) back in real time. One WebSocket, ISO codes sr to uk, and ultra-low latency for voice agents and live apps.

Trusted by teams building global voice products

Production-ready Serbian to Ukrainian translation API

Real Serbian 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.

Serbian (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.
