French to Lithuanian speech translation API

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

Trusted by

Production-ready French to Lithuanian translation API

Real French 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.

French (Indo-European > Romance > Western Romance) 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.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
