Offline French voice translator.
No internet. No subscription.

Speak your language — your phone speaks French (Français), in your own voice.

~310 million speakers · spoken across France, Canada, Belgium, Switzerland, and most of West and Central Africa

French is an official language in 29 countries — it's as useful in Dakar and Abidjan as in Paris. Rasterdeck Translator speaks it fluently in both directions, offline, with your own voice cloned so a conversation still sounds like you.

On the road

One language that covers Paris, Montréal, Geneva, Brussels, and half of Africa — without roaming data.

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

3

It speaks French

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

French translation — common questions

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