Production-ready Thai to Finnish translation API

Real Thai 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.

Thai (Kra-Dai > Tai) 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.

Thai is written in Thai and Finnish in Latin, so Soniox emits correctly scripted Finnish text.

Real-time Thai to Finnish translation

Soniox streams the Thai 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 Thai to Finnish with the API?
Add a translation block to your real-time request with source_language "th" and target_language "fi". Soniox transcribes Thai and streams the Finnish translation over the same WebSocket.
Is Thai to Finnish translation real-time?
Yes. Soniox streams Finnish while Thai is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating Finnish to Thai?
That direction is supported too. See the Finnish to Thai page, or use two-way translation to run both directions in one session.
Does Soniox handle Thai to Latin output?
Yes. Soniox outputs correctly scripted Finnish text in Latin directly in the token stream.
Does Soniox handle Thai dialects and accents?
Yes. Soniox handles Thai dialects like Central Thai, Northern Thai, and Northeastern Thai (Isan) in a single model, so Finnish translation stays accurate across regions.
Which other providers support Thai to Finnish?
Based on their public docs, OpenAI and Azure list both Thai and Finnish for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Thai to Finnish translation?
Soniox streams Finnish as Thai is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
