# nihongo.stream speech files
On-device speech recognition files for the **Kana Trainer** game of
nihongo.stream, a static website of games for learning Japanese.
The website downloads these files straight into the visitor's browser, which runs them
offline. No server or account is involved.
Everything here is an unmodified copy of a public release. The layout is made by
`scripts/fetch-speech.sh` in the nihongo.stream repository.
