Dutch to Bengali speech translation API

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

Trusted by

Production-ready Dutch to Bengali translation API

Real Dutch 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.

Dutch (Indo-European > Germanic > West Germanic) 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.

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