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

Trusted by

Production-ready Welsh to Ukrainian translation API

Real Welsh 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.

Welsh (Indo-European > Celtic > Brittonic) 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.

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

Welsh and Ukrainian through a single stream

Welsh 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.

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