Python 读取 mp3 文件时遇到问题

Question

import speech_recognition as sr
print(sr.__version__)
r = sr.Recognizer()

file_audio = sr.AudioFile('damn1.mp3')

with file_audio as source:
   audio_text = r.record(source)

print(type(audio_text))
print(r.recognize_google(audio_text))

我有一个问题运行这个程序。我得到的输出如下：

Traceback (most recent call last):
  File "C:\Users\kubar\AppData\Local\Programs\Python\Python38-32\lib\site-packages\speech_recognition\__init__.py", line 203, in __enter__
    self.audio_reader = wave.open(self.filename_or_fileobject, "rb")
  File "C:\Users\kubar\AppData\Local\Programs\Python\Python38-32\lib\wave.py", line 510, in open
    return Wave_read(f)
  File "C:\Users\kubar\AppData\Local\Programs\Python\Python38-32\lib\wave.py", line 164, in __init__
    self.initfp(f)
  File "C:\Users\kubar\AppData\Local\Programs\Python\Python38-32\lib\wave.py", line 131, in initfp
    raise Error('file does not start with RIFF id')
wave.Error: file does not start with RIFF id

在处理上述异常的过程中，又发生了异常：

MP3 是一种压缩格式。处理音频时切勿使用它，因为大多数处理音频的工具都是在非压缩音频流上进行的。因此，即使此类工具接受了您的文件，它也可能从转换文件开始，这会消耗时间和空间。此外，MP3 从未被从事音频工作的专业人员（音乐家、工程师等）使用：避免将其与对您的工作有一定重要性的音频材料一起使用（即使用于存档，因为压缩是不可逆的），总是喜欢使用非压缩格式改为 WAV 或 AIF（这里的图书馆似乎期望 AIF）。
