Trusted by teams building global voice products
Production-ready Ukrainian to Japanese translation API
Real Ukrainian speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Japanese while the speaker is still talking.
Ukrainian (Indo-European > Slavic > East Slavic) and Japanese (Japonic) 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 Japanese in CJK, so Soniox emits correctly scripted Japanese text.

}Ukrainian and Japanese through a single stream
Ukrainian to Japanese translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Japanese 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: "ja". It runs on the same WebSocket and the same model, with no extra round trip.
