Answer 1

Your code is no problem.
It can run successfully on my Windows 10, my python version is 3.7.3.
ImportError: DLL load failed while importing win32api: The specified module could not be found.
Your win32api module does not seem to be installed correctly, please use pip uninstall pywin32 to uninstall and use pip install pywin32 to install again.
You can also refer other methods in the link to solve it.
For KeyError: None, you can refer Python KeyError Exceptions and How to Handle Them to do some error handling.
Finally, please follow this tutorial to convert text to speech.

Answer 2

I sloved my own problem.
Firstly! I uninstalled Python-3.8 from control panel and installed Python-3.7.2(and added to path during installation).
Secondly,Upgraded setuptool using cmd -> pip install --upgrade setuptools.
after that I installed SpeechRecognition, pyttsx3
and after that I also installed
PyAudio-0.2.11-cp37-cp37m-win_amd64.whl using whl file(because pyaudio is necessary to run this program).
Link to download whl file-> Here .
Now, This program works.
