Offline Japanese voice translator.
No internet. No subscription.
Speak your language — your phone speaks Japanese (日本語), with Pro voice cloning after setup.
~125 million speakers · spoken across Japan
Japanese is consistently rated the hardest major language for English speakers — three writing systems and grammar that reverses everything. It's also a country where English fluency is rarer than visitors expect. Spoken translation running locally on your phone bridges izakaya menus, train mishaps, and actual conversations with people you meet.
On the road
Tokyo has English signage; the onsen town three hours north does not. Neither needs a connection.
Good to know
Try speech recognition on your phone before choosing a tier. Pro includes larger recognition models; results depend on the language, recording and device.
How Japanese translation works on-device
1
You speak or type
Choose your languages, then enter text or use voice input. Conversation processing runs on your phone after setup.
2
It translates
An on-device neural model translates to Japanese (or from Japanese to your language) with no server round-trip.
3
It speaks Japanese
With Pro and the required models installed, your phone can speak the translation using the speaker's voice. Try the language pair on your phone before choosing an unlock.
