Hlas / How to dictate in Czech on a Mac

How to dictate in Czech on a Mac

You can dictate Czech on a Mac with built-in macOS dictation, or with Hlas, which transcribes with Whisper on your computer, also offline, and types into any app.

Who is this for?

Foreigners writing in Czech, companies with Czech teams and anyone who switches between Czech and English. Hlas keeps háčky and čárky in place thanks to a Czech priming prompt.

How do I start?

Download Hlas, allow the microphone and Accessibility, pick the local model, then hold Fn, speak and release.

Can I mix Czech and English?

Yes. Pin both languages or leave Hlas on auto-detect; English terms inside Czech sentences stay intact, and you can add names to the vocabulary.
