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.

Real-time Estonian to Finnish translation

Soniox streams the Estonian transcript and the Finnish translation on the same connection, word by word, so meaning lands while the speaker is still talking.

Frequently asked questions

How do I translate Estonian to Finnish with the API?
Add a translation block to your real-time request with source_language "et" and target_language "fi". Soniox transcribes Estonian and streams the Finnish translation over the same WebSocket.
Is Estonian to Finnish translation real-time?
Yes. Soniox streams Finnish while Estonian is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating Finnish to Estonian?
That direction is supported too. See the Finnish to Estonian page, or use two-way translation to run both directions in one session.
Estonian and Finnish are both Uralic > Finnic — does that affect quality?
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.
Does Soniox handle Estonian dialects and accents?
Yes. Soniox handles Estonian dialects like North Estonian, South Estonian, and Northeastern Coastal Estonian in a single model, so Finnish translation stays accurate across regions.
Which other providers support Estonian to Finnish?
Based on their public docs, OpenAI, Azure, and Speechmatics list both Estonian and Finnish for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Estonian to Finnish translation?
Soniox streams Finnish as Estonian is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
