Production-ready Bengali to Vietnamese translation API

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

Bengali (Indo-European > Indo-Aryan > Eastern) and Vietnamese (Austroasiatic > Vietic) 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 Vietnamese in Latin, so Soniox emits correctly scripted Vietnamese text.

Real-time Bengali to Vietnamese translation

Soniox streams the Bengali transcript and the Vietnamese translation on the same connection, word by word, so meaning lands while the speaker is still talking.
