獲取long_running_recognize操作的進度（Google Cloud Speech API）

Question

我的代碼很簡單。 它在單個通道的FLAC音頻文件上運行long_running_recognize ，並使用Google Cloud Speech API存儲結果。 我正在嘗試找到一種方法來獲取long_running_recognize操作的當前進度。 我找到了有關該主題的一些文檔，但是很難理解。

client = speech.SpeechClient()
operation = client.long_running_recognize(
  audio = speech.types.RecognitionAudio(
    uri = str('gs://speech-clips/'+self.audio_fqid),
  ),
  config = speech.types.RecognitionConfig(
    encoding = enums.RecognitionConfig.AudioEncoding.FLAC,
    sample_rate_hertz = sample_rate,
    enable_word_time_offsets = True,
    language_code = 'en-US',
  ),
)
response = operation.result()

這是我發現的一些文檔：

• https://cloud.google.com/speech/reference/rest/v1/LongRunningRecognizeMetadata
• https://cloud.google.com/speech/reference/rpc/google.longrunning#google.longrunning.Operations.GetOperation
• https://cloud.google.com/speech/reference/rest/v1beta1/operations

任何幫助將不勝感激。

由於長時間的音頻識別是一個漫長的過程，因此API將為您提供一個令牌，該令牌即為操作響應中的name ，一旦該過程完成，則done將變為true 。 我使用RESTful API來執行請求，希望它可以為您工作：

這是偽代碼：

    import googleapiclient.discovery
    import time
    service = googleapiclient.discovery.build('speech', 'v1')
    service_request = service.speech().longrunningrecognize(
        body= {
            "config": {
                "encoding": "FLAC",
                "languageCode": "en-US",
                "enableWordTimeOffsets": True
            },
            "audio": {
                "uri": str('gs://speech-clips/'+self.audio_fqid)
            }
        }
    )
    operation = service_request.execute()

    name = operation['name']
    service_request = service.operations().get(name=name)
    while True:

        # Give the server a few seconds to process.

        print('Waiting for server processing...')

        time.sleep(1)

        # Get the long running operation with response.

        response = service_request.execute()

        if 'done' in response and response['done']:
            break
    return response
