Ukrainian to Polish speech translation API

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

Trusted by

Production-ready Ukrainian to Polish translation API

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

Ukrainian (Indo-European > Slavic > East Slavic) and Polish (Indo-European > Slavic > West Slavic) 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 Polish in Latin, so Soniox emits correctly scripted Polish text.

Ukrainian and Polish through a single stream

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

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