错误: NotImplementedError:这是语音识别中的抽象类

Question

我是编程新手，几周前我开始学习如何编写Python。我一直在用speech_recognition进行测试，我总是会遇到这个错误，这个错误已经困扰我好几天了。我在Windows上使用的是Python 3.9.5。

import speech_recognition

ai_ear = speech_recognition.Recognizer()
with speech_recognition.Recognizer() as mic:
    print("AI: I'm listening...")
    audio = ai_ear.listen(mic)

try:
    you = ai_ear.recognize_google(audio)
except:
    you = ""

you = ai_ear.recognize_google(audio)

print(you)

Traceback (most recent call last):

  File "C:\Users\Admin\Documents\Python Projects\3-AI.py", line 4, in <module>
    with speech_recognition.Recognizer() as mic:
  File "C:\Users\Admin\AppData\Local\Programs\Python\Python39\lib\site-packages\speech_recognition\__init__.py", line 51, in __enter__
    raise NotImplementedError("this is an abstract class")
NotImplementedError: this is an abstract class

附言:你能不能提前告诉我“抽象类”是什么意思？

Answer 1

抽象类意味着类必须被继承。抽象方法本身不会做任何事情。
