Error in google cloud speech api synchronous speech recognition docs
我将 https://cloud.google.com/speech/docs/sync-recognize 上的谷歌云语音 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，我收到了很多错误数：

这是我的代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | import os import io def transcribe_file(speech_file): """Transcribe the given audio file.""" from google.cloud import speech from google.cloud.speech import enums from google.cloud.speech import types client = speech.SpeechClient() with io.open(speech_file, 'rb') as audio_file: content = audio_file.read() audio = types.RecognitionAudio(content=content) config = types.RecognitionConfig( encoding=enums.RecognitionConfig.AudioEncoding.LINEAR16, sample_rate_hertz=16000, language_code='en-US') response = client.recognize(config, audio) # Each result is for a consecutive portion of the audio. Iterate through # them to get the transcripts for the entire audio file. for result in response.results: # The first alternative is the most likely one for this portion. print('Transcript: {}'.format(result.alternatives[0].transcript)) print (transcribe_file("output.wav")) |
有人可以帮我解决这个错误吗？
以下是接受 sorak 建议后的第二批错误：

错误信息似乎在抱怨：
1 | 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
1 | must either be omitted or match the value in the WAV header |
...如果你只是删除那行会发生什么？
