English to Ukrainian speech translation API

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

Trusted by

Production-ready English to Ukrainian translation API

Real English 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.

English (Indo-European > Germanic > West Germanic) 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.

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

English and Ukrainian through a single stream

English to Ukrainian translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Ukrainian translation streams mid-sentence in the same labeled token stream.
