Offline Portuguese voice translator.
No internet. No subscription.

Speak your language — your phone speaks Portuguese (Português), in your own voice.

~260 million speakers · spoken across Brazil, Portugal, Angola, and Mozambique

Portuguese is the most-spoken language of the southern hemisphere, and Brazilian and European Portuguese diverge enough to trip up basic tools. Rasterdeck Translator covers real spoken Portuguese on-device — useful from Lisbon trams to Brazilian beach towns where data plans die.

On the road

Rio, the Azores, or the Angolan coast — the same offline translator works in all of them.

How Portuguese 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 Portuguese (or from Portuguese to your language) with no server round-trip.

3

It speaks Portuguese

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

Portuguese translation — common questions

Does the Portuguese translation work without internet?
Yes — completely. Speech recognition, translation, and spoken output for Portuguese 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 Portuguese 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 Portuguese?
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 Portuguese 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 Portuguese.
