Catalan to Bengali speech translation API

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

Trusted by

Production-ready Catalan to Bengali translation API

Real Catalan 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.

Catalan (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.

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

Catalan and Bengali through a single stream

Catalan to Bengali translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Bengali translation streams mid-sentence in the same labeled token stream.

Turn it on by adding a translation block with source_language: "ca" and target_language: "bn". It runs on the same WebSocket and the same model, with no extra round trip.
