Provides offline speech recognition features for the Freeswitch based on whisper_cpp.
Was capable to work with the first versions of whisper_cpp (not longer supported)
Capable to work with the latest version whisper_cpp (revelant on the date: 12.06.2024)

The issues: unfortunately i don't have enough time (now) to deeply dig what is going on, mb it's my mistake somewhere there.
But have the follogin (although the same time the whisperd works well):
