SpeechContext 没有“提升”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提升字段。

我把导入的speech_v1p1beta1改成了speech_v1，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)
  File "/env/lib/python3.5/site-packages/google/protobuf/internal/python_message.py", line 573, in _GetFieldByName
    (message_descriptor.name, field_name))
ValueError: Protocol message SpeechContext has no "boost" field.```

Answer 1

我通过更新系统中的 beta 库解决了这个问题。我是通过谷歌从 github 代码中复制代码来做到这一点的。

您似乎正在使用包“speech”的 RecognitionConfig，而不是“speech_v1p1beta1”。如果使用 beta 功能，还应该从 Speech_v1p1beta1 包中导入类型和枚举。您的导入语句应如下所示：

from google.cloud import speech_v1p1beta1
from google.cloud.speech_v1p1beta1 import enums
from google.cloud.speech_v1p1beta1 import types
