New: Soniox v5 Real-Time is here
Build with API

Portuguese to Finnish speech translation API

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

Trusted by teams building global voice products

Production-ready Portuguese to Finnish translation API

Real Portuguese 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.

Portuguese (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.

Portuguese and Finnish through a single stream

Portuguese 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: "pt" and target_language: "fi". It runs on the same WebSocket and the same model, with no extra round trip.
