Question

我的编程能力很有限，所以我事先表示歉意。

我正在尝试通过流音频接收DialogFlow的意图。我正在用麦克风对其进行测试。

我引用了以下Google示例代码。

Microphone Streaming Audio for Google STT

两者都能正常工作，但是当我尝试将两个示例代码结合在一起时，会出现以下错误。

No handlers could be found for logger "grpc._channel"
Traceback (most recent call last):
  File "detect_intent_stream.py", line 181, in <module> detect_intent_stream(project_id, session_id, language_code)
  File "detect_intent_stream.py", line 162, in detect_intent_stream for response in responses:
  File "C:\Python27\lib\site-packages\google\api_core\grpc_helpers.py", line 83, in next six.raise_from(exceptions.from_grpc_error(exc), exc)
  File "C:\Python27\lib\site-packages\six.py", line 737, in raise_from raise value
google.api_core.exceptions.Unknown: None Exception iterating requests!

我正在寻找解决方案，因此遇到了这篇文章。但是我不确定如何执行所提供的建议。

Intermediate results on using session_client.streaming_detect_intent()

下面是我目前的代码。

def detect_intent_stream(project_id, session_id, language_code):
    import dialogflow_v2 as dialogflow
    session_client = dialogflow.SessionsClient()

    audio_encoding = dialogflow.enums.AudioEncoding.AUDIO_ENCODING_LINEAR_16
    sample_rate_hertz = 8000

    session_path = session_client.session_path(project_id, session_id)

    def request_generator(audio_config):
        query_input = dialogflow.types.QueryInput(audio_config=audio_config)
        yield dialogflow.types.StreamingDetectIntentRequest(session=session_path, query_input=query_input, single_utterance=True)

        with MicrophoneStream(RATE, CHUNK) as stream:
            #while True:
            #Temp condition
            while dialogflow.types.StreamingRecognitionResult().is_final == False:
                audio_generated = stream.generator()
                #Temp condition
                if not audio_generated:
                    break
                yield dialogflow.types.StreamingDetectIntentRequest(input_audio=audio_generated)

    audio_config = dialogflow.types.InputAudioConfig(audio_encoding=audio_encoding, language_code=language_code, sample_rate_hertz=sample_rate_hertz)

    requests = request_generator(audio_config)
    responses = session_client.streaming_detect_intent(requests)

    print('=' * 20)
    for response in responses:
        print('Intermediate transcript: "{}".'.format(response.recognition_result.transcript)).encode('utf-8')

    query_result = response.query_result

    print('=' * 20)
    print('Query text: {}'.format(query_result.query_text))
    print('Detected intent: {} (confidence: {})\n'.format(
        query_result.intent.display_name,
        query_result.intent_detection_confidence))
    print('Fulfillment text: {}\n'.format(
        query_result.fulfillment_text))

编辑：我已经固定了参考代码。

解决了！

所以问题是STT函数StreamingRecognizeRequest和DF函数StreamingDetectIntentRequest接受了不同的参数。

STT函数将生成器作为参数，而DF函数将实际缓冲区作为参数。
