Bengali to Indonesian speech translation API

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

Trusted by

Production-ready Bengali to Indonesian translation API

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

Bengali (Indo-European > Indo-Aryan > Eastern) and Indonesian (Austronesian > Malayo-Polynesian > Malay) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

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