How a full translator runs on your phone

Download the models during setup, then recognition, translation and playback run on your phone. Activation and purchase verification use the network. Here is what each translation step does and how to check it on your device.

The pipeline

1 · Listen — Speech recognition
The app turns speech into text on the phone. It uses local recognition models after they have been downloaded. Longer speech may take more time than a short phrase.
2 · Translate — Local translation model
The recognized text is translated on the phone. Language availability depends on the feature: 42 for typed text and 40 for voice.
3 · Speak — Spoken playback
The phone reads the translation aloud in supported languages. Pro adds per-speaker voice cloning in 28 languages. Listen to a free sample on your own device before choosing an unlock.
4 · Read — Photo text recognition
Photo Translate reads text from a camera image and translates it on the device in 40 languages. Results depend on the image, script, lighting and phone.

Set up and check offline use

Install the app and download the models you need while connected to Wi-Fi. Try a short translation in your languages. Then turn on airplane mode and repeat the same task. Spoken output depends on the voices installed on your phone; 16 or more languages have free device voices.

If you want unlimited voice use or Pro voice cloning, activate the appropriate phone-bound code while connected. Once the models are installed, translation content is processed on the device. Speed and accuracy vary by phone, language and input; the free trial is the best way to check your own use case.
