谷歌语音 API Python 无响应

Question

I'm trying to implement google's speech api but every time I try to run the program, the terminal goes unresponsive. It seems that the program runs until the line "response = client.recognize(config, audio)" and just gets stuck at that point. Here's a picture of my code, I pulled most of it straight from google's cloud platform documentation.

def transcribe_file(speech_file):

    import os
    import io
    os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="api-key.json"

    """Transcribe the given audio file."""
    from google.cloud import speech
    from google.cloud.speech import enums
    from google.cloud.speech import types
    import io
    client = speech.SpeechClient()

    with io.open(speech_file, 'rb') as audio_file:
        content = audio_file.read()

    audio = types.RecognitionAudio(content=content)
    config = types.RecognitionConfig(
        encoding='FLAC',
        sample_rate_hertz=16000,
        language_code='en-US')

    print(config)

    response = client.recognize(config, audio)

    # Each result is for a consecutive portion of the audio. Iterate through
    # them to get the transcripts for the entire audio file.
    for result in response.results:
        # The first alternative is the most likely one for this portion.
        print(u'Transcript: {}'.format(result.alternatives[0].transcript))

transcribe_file(audio/file/name.wav)

Answer 1

I had the same problem when building my app with PyInstaller. Make sure you have the certifi folder with the file cacert.pem in it. Those should come with the library when you run pip install google-cloud-speech . If not reinstall it.

Answer 2

I was facing the same issue, tried changing

os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="api-key.json"

to

os.environ["GOOGLE_APPLICATION_CREDENTIALS"]= r"full/path/api-key.json"

on window .
