在Python中将音频转换为文本时出错

Question

我正在尝试将音频文件转换为文本。音频保存为桌面上的Wel.wav。在

代码如下：

import speech_recognition as sr

r = sr.Recognizer()

audio = 'Wel.wav'

with sr.AudioFile(audio) as source:
audio = r.record(source)
print ('Done!')

try:
text = r.recognize_google(audio)
print (text)

except Exception as e:
print (e)

我得到以下错误：

^{pr2}$

现在当我试着告诉它目录位置时

我把音频命令改成

audio = 'C:\\Users\\user\\Desktop\\Wel.wav'

它抛出以下错误：

有谁能帮我一下吗。在
