What does HackerNews think of LiveCaptions?
Linux Desktop application that provides live captioning
Language:
C
https://github.com/abb128/LiveCaptions comes to mind: The libraries and models for it are easily available for reworking it to be how you want, and can run 24/7 if you don't mind the cpu usage
Not Whisper per se, but IIRC LiveCaptions is partially trained using Whisper. It also works really well!
There is this app [1] which works well but is English-only unfortunately. Still looks cool though.
