French to Finnish speech translation API

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

Trusted by

Production-ready French to Finnish translation API

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

French (Indo-European > Romance > Western Romance) and Finnish (Uralic > Finnic) 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.

French and Finnish through a single stream

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

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