Live Vietnamese speech translation API

Production-ready Vietnamese speech translation API

Real conversations in Vietnamese include accents, regional dialects, code switching, and domain-specific vocabulary. Soniox is built to handle that variation in a single model, so live translation stays usable across regions and registers.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Vietnamese belongs to the Austroasiatic > Vietic family. Soniox translates between Vietnamese and any of 60+ supported targets and 3,600 language pairs in total.

High quality Vietnamese output

Same model across every language, including historically underserved ones.

Native-speaker Vietnamese STT accuracy

Vietnamese names, numbers, and domain terms

Preserved in both transcript and translation, including phone numbers, emails, and IDs.

Vietnamese translation is built on top of the Soniox Speech-to-Text API. Turn it on by adding a translation block to your request. Translated tokens come back interleaved with transcripts on the same stream, with no extra round trip.

Vietnamese speech-to-speech translation

Build full spoken Vietnamese translation by combining Soniox STT and Soniox TTS. Soniox recognizes Vietnamese, translates it in real time, and speaks the output in the target language with low latency.

Use it for live Vietnamese interpreters, bilingual voice agents, travel assistants, customer support, and real-time multilingual communication.

One-way or two-way Vietnamese translation

One-way translates all speech into a single target language. Two-way keeps a bilingual conversation flowing between Vietnamese and another language, so each side speaks naturally and hears the other in their own.
