Offline Vietnamese voice translator.
No internet. No subscription.

Speak your language — your phone speaks Vietnamese (Tiếng Việt), in your own voice.

~85 million speakers · spoken across Vietnam and large communities in the US, Australia, and Europe

Vietnamese is a tonal language — the same syllable means six different things depending on pitch — which makes it nearly impossible to fake from a phrasebook. Speech-to-speech translation sidesteps tones entirely: you talk, your phone produces real Vietnamese.

On the road

Street food in Hanoi, motorbike rentals in Da Nang, homestays in the Mekong Delta — mostly cash, often offline.

How Vietnamese translation works on-device

1

You speak

The app transcribes your speech locally — the audio never leaves your phone's memory.

2

It translates

An on-device neural model translates to Vietnamese (or from Vietnamese to your language) with no server round-trip.

3

It speaks Vietnamese

Your phone speaks the translation aloud — in a clone of the speaker's own voice. The conversation still sounds like the people having it.

Vietnamese translation — common questions

Does the Vietnamese translation work without internet?
Yes — completely. Speech recognition, translation, and spoken output for Vietnamese all run on your phone. Airplane mode, foreign SIM-card limbo, basement, mountain, mid-flight: it all works, because nothing is sent anywhere.
Is my spoken Vietnamese audio uploaded or stored?
No. Audio is processed in memory on your device and discarded after the translation plays. No audio, text, or metadata is transmitted or written to disk. The app has no account system and no telemetry.
Do I need a subscription to translate Vietnamese?
No. The app is a free download with a full-featured trial. One single payment unlocks unlimited use for the lifetime of your phone — no subscription, no renewal, no expiry.
How natural does the translated Vietnamese voice sound?
It sounds like the person speaking. The app clones each speaker's voice — no enrollment or voice samples — so a translated conversation keeps each person's actual voice in Vietnamese.
