Production-ready Vietnamese to Bengali translation API

Real Vietnamese 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.

Vietnamese (Austroasiatic > Vietic) 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.

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

Real-time Vietnamese to Bengali translation

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