Lithuanian to Russian speech translation API

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

Trusted by

Production-ready Lithuanian to Russian translation API

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

Lithuanian (Indo-European > Baltic) and Russian (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.

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

Lithuanian and Russian through a single stream

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