Lithuanian to French speech translation API

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

Trusted by

Production-ready Lithuanian to French translation API

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

Lithuanian (Indo-European > Baltic) and French (Indo-European > Romance > Western Romance) 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.
