Offline Japanese voice translator.
No internet. No subscription.
Speak your language — your phone speaks Japanese (日本語), in your own voice.
~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
Spoken Japanese output uses the Pro upgrade's premium voices — the standard tier translates Japanese speech and shows text, but doesn't yet speak it aloud.
How Japanese 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 Japanese (or from Japanese to your language) with no server round-trip.
3
It speaks Japanese
Your phone speaks the translation aloud — in a clone of the speaker's own voice. The conversation still sounds like the people having it.
