French to Bengali speech translation API

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

Trusted by

Production-ready French to Bengali translation API

Real French 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.

French (Indo-European > Romance > Western Romance) 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.

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