Mac Big sur 11.2.3 with python3

I have installed python3.9.
I try to build a python script for speechRecognition.

I installed
pip install SpeechRecognition
brew install audioport
pip3 install pyaudio

Then copy an paste from a copple of examples: I.G.

Code Block 
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

and so on.
What i get all time is an error. Most like:

Code Block 
||PaMacCore (AUHAL)|| Error on line 1277: err='-66748', msg=Unknown Error
Traceback (most recent call last):
  File "/Users/horst/VisualStudioCodeWork/Python_Projects/Amelie_03/SpeechRecognition.py", line 9, in <module>
    with sr.Microphone() as source:
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/speech_recognition/__init__.py", line 87, in __enter__
    self.stream = self.audio.open(
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pyaudio.py", line 750, in open
    stream = Stream(self, *args, kwargs)
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/pyaudio.py", line 441, in __init__
    self._stream = pa.open(arguments)
OSError: [Errno -9986] Internal PortAudio error

I have googled so many time. Reinstall, and install. Follow all tips. Finally i have no idea more.

Is there anybody can help?
Thanks in advanced.

P.S. On Linux all works fine. Why not on mac?

Edit:
I found this on stackoverflow:
brew uninstall portaudio
brew install portaudio --HEAD

• -HEAD was the solution for leav the error ((OMG)) :(

but now i get'nt signal from microphon :(
I'm very frustrated.
