Finnish to Bengali speech translation API

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

Trusted by

Production-ready Finnish to Bengali translation API

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

Finnish (Uralic > Finnic) and Bengali (Indo-European > Indo-Aryan > Eastern) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

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

Finnish and Bengali through a single stream

Finnish to Bengali translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Bengali 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: "bn". It runs on the same WebSocket and the same model, with no extra round trip.
