Question

我正在使用Google Cloud API进行语音文本转换，我想添加一些上下文短语。根据google文档，语音上下文还具有一个我无法设置的boost字段。

我更改了导入的Speech_v1p1beta1而不是Speech_v1，并进行了如下编码：

    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            
    #         )
    #         ]
    )

我遇到以下错误：

  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}]
  File "/env/lib/python3.5/site-packages/google/protobuf/internal/python_message.py", line 528, in init
    copy.add(**val)
  File "/env/lib/python3.5/site-packages/google/protobuf/internal/containers.py", line 376, in add
    new_element = self._message_descriptor._concrete_class(**kwargs)
  File "/env/lib/python3.5/site-packages/google/protobuf/internal/python_message.py", line 509, in init
    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库解决了此问题。我是通过Google从github代码中复制代码来做到这一点的。

Answer 2

似乎您正在使用软件包“ speech”的RecognitionConfig，而不是“ speech_v1p1beta1 ”。如果使用beta功能，则类型和枚举也应从speech_v1p1beta1包中导入。您的导入语句应类似于：

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

SpeechContext没有“ boost”字段
