谷歌云语音api同步语音识别文档出错

Question

我将位于https://cloud.google.com/speech/docs/sync-recognize的google cloud speech api同步语音识别文档中的信息复制到我的代码中，但是当我运行代码时，我收到了很多错误：

Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/google/gax/retry.py", line 121, in inner

During handling of the above exception, another exception occurred:

有人能帮我修正这个错误吗？在

以下是接受索拉克建议后的第二批错误：

Answer 1

错误消息似乎在抱怨：

sample_rate_hertz=16000

因为它指定的采样率与标准wav采样率44100冲突。它说这个值

。。。如果你把那条线去掉会怎么样？在
