Build with API

Finnish to Norwegian speech translation API

Stream Finnish (Suomi) speech and get Norwegian (Norsk) back in real time. One WebSocket, ISO codes fi to no, and ultra-low latency for voice agents and live apps.

Trusted by teams building global voice products

Production-ready Finnish to Norwegian translation API

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

Finnish (Uralic > Finnic) and Norwegian (Indo-European > Germanic > North Germanic) 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.

Finnish and Norwegian through a single stream

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

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