I had to make changes for not getting stuck at engine.runAndWait()

[corgok]

On a windows computer, engine.runAndWait() did not continue after speaking. I moved the engine = pyttsx3.init() in front of the current line 31 and added engine = None and
rate = None to the current lines 23/24 and now it works.

Addintionally, getting ffmpeg to work, required an installation that is described in the openai-whisper description.
