Urdu to Bengali speech translation API

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

Trusted by

Production-ready Urdu to Bengali translation API

Real Urdu 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.

Urdu (Indo-European > Indo-Aryan > Central) 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.

Urdu is written in Arabic and Bengali in Bengali, so Soniox emits correctly scripted Bengali text. Right-to-left output is handled directly in the token stream.
