Russian to Lithuanian speech translation API

Stream Russian (Русский) speech and get Lithuanian (Lietuvių) back in real time. One WebSocket, ISO codes ru to lt, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Russian to Lithuanian translation API

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

Russian (Indo-European > Slavic > East Slavic) and Lithuanian (Indo-European > Baltic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Russian is written in Cyrillic and Lithuanian in Latin, so Soniox emits correctly scripted Lithuanian text.

Russian and Lithuanian through a single stream

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

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