Czech has seven grammatical cases and consonant clusters that defeat phrasebooks. A neural model running on your phone handles real spoken Czech in both directions — and keeps working in the castle basement and the night train where data doesn't.

On the road

Prague beyond the tourist core, Moravian wine country, and trains to the borderlands.

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

3

It speaks Czech

Your phone speaks the translation aloud using its built-in Czech voices, where your device has them. Recognition and translation are always on-device.

Czech translation — common questions

Does the Czech translation work without internet?
Yes — completely. Speech recognition, translation, and spoken output for Czech 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 Czech 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 Czech?
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.
Does Czech speak the translation aloud?
Yes — spoken Czech output uses your phone's own text-to-speech voices, so how it sounds depends on the Czech voices installed on your device. Per-speaker voice cloning is reserved for the core languages; for Czech, recognition and translation always run fully offline, and you can hear exactly how it sounds on your phone during the free trial.
