Estonian to Finnish speech translation API

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

Trusted by

Production-ready Estonian to Finnish translation API

Real Estonian 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.

Estonian and Finnish both belong to the Uralic > Finnic family, so cognates and shared structure carry over cleanly into the translated Finnish output.

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

Estonian and Finnish through a single stream

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

Estonian and Finnish are both Uralic > Finnic — does that affect quality?arrow_downward
Shared family structure and cognates generally help. Soniox uses the same model for every pair, so quality stays consistent whether the languages are closely related or not.
