Indonesian to Bengali speech translation API

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

Trusted by

Production-ready Indonesian to Bengali translation API

Real Indonesian 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.

Indonesian (Austronesian > Malayo-Polynesian > Malay) 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.

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