Trusted by teams building global voice products
Production-ready Bengali to Hindi translation API
Real Bengali speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Hindi while the speaker is still talking.
Bengali (Indo-European > Indo-Aryan > Eastern) and Hindi (Indo-European > Indo-Aryan > Central) 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 Hindi in Devanagari, so Soniox emits correctly scripted Hindi text.

}Bengali and Hindi through a single stream
Bengali to Hindi translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Hindi translation streams mid-sentence in the same labeled token stream.
Turn it on by adding a translation block with source_language: "bn" and target_language: "hi". It runs on the same WebSocket and the same model, with no extra round trip.
