AttributeError: __Enter__ - How to use?

Question

我正在尝试在Python中制作一个简单的语音识别工具，并尝试了以下代码：

import speech_recognition as sr

r = sr.Recognizer()

with sr.Microphone as source:
print ("Speak into the microphone")
audio = r.listen(source) 

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-4-10651df1693e> in <module>
----> 1 with sr.Microphone as source:
      2     print ("Speak into the microphone")
      3     audio = r.listen(source)

AttributeError: __enter__ 

我希望有人能够阐明如何在这种情况下使用 __enter__ 属性？

非常感谢！

下面是使用 google 识别器的代码，它将持续监听直到您终止：

import speech_recognition as sr

def speech_recog():
    r = sr.Recognizer()

    mic = sr.Microphone()
    while True:
        with mic as source:
            print("Speak...")

            audio = r.listen(source)

            try:
                text = r.recognize_google(audio)
                print(f"You said {text}")

            except sr.UnknownValueError:
                print("Didnt hear that try again")
speech_recog()

如果您只想听一个实例，请删除：

while True:
