AttributeError：模块“ _portaudio”没有属性“ paFloat32”

Question

顺便说一句，paFloat32表示portaudioFloat32
我正在尝试使用Speech_recognition库，安装了PyAudio，但是当我运行脚本时出现此错误：

Traceback (most recent call last):
  File "C:\Users\User\!Python!\0.8.py", line 6, in <module>
    with sr.Microphone() as source:
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\speech_recognition\__init__.py", line 79, in __init__
    self.pyaudio_module = self.get_pyaudio()
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\speech_recognition\__init__.py", line 108, in get_pyaudio
    import pyaudio
  File "C:\Users\User\AppData\Local\Programs\Python\Python38\lib\site-packages\pyaudio.py", line 127, in <module>
    paFloat32      = pa.paFloat32      #: 32 bit float
AttributeError: module '_portaudio' has no attribute 'paFloat32'

我的代码：

r = sr.Recognizer()
with sr.Microphone() as source:
    audio = r.listen(source)
    said = ''
        
    try:
        said = r.recognize_google(audio, language="en-EN")
        print(said)
    except sr.UnknownValueError:
        print("Unrecognised speech")

这很容易，而且必须能正常工作，但不能（我已经在Google搜索此错误，却一无所获
我在Windows 10上使用Python 3.8.5（64位）
