google-cloud-platform - SpeechContext 没有 "boost"字段

Question

我正在使用 google cloud api 进行语音转文本，我想添加一些上下文短语。根据谷歌文档，语音上下文也有一个我无法设置的增强字段。

我更改了导入的 speech_v1p1beta1 而不是 speech_v1 并编码如下:

    config = speech.RecognitionConfig(
    encoding=speech.RecognitionConfig.AudioEncoding.LINEAR16,

    sample_rate_hertz=8000,
    language_code=first_lang,
    #alternative_language_codes=[second_lang],
    audio_channel_count=1,
    enable_separate_recognition_per_channel=False,
    #metadata=metadata,
    max_alternatives=5,
    # enable_word_confidence=True,

    speech_contexts=[{'phrases':['sfs'],'boost':15}]


    # speech_contexts=[speech.SpeechContext(
    #         phrases=['life insurance'],boost=15            
    #         )
    #         ]
    )

我收到以下错误:

  File "convert-wav-beta.py", line 165, in <module>
    transcript , confidence = google_transcribe(audio_file_name)
  File "convert-wav-beta.py", line 106, in google_transcribe
    speech_contexts=[{'phrases':['sfs'],'boost':15}]

    field = _GetFieldByName(message_descriptor, field_name)

    (message_descriptor.name, field_name))
ValueError: Protocol message SpeechContext has no "boost" field.```

我通过更新系统中的 beta 库解决了这个问题。我通过从 google 的 github 代码复制代码来做到这一点。
