如何使用python从google云读取mp3数据

Question

我正在尝试从谷歌云读取mp3/wav数据，并尝试实现音频数字化技术。问题是我无法读取google在变量响应中传递的结果。

下面是我的python代码

speech_file = r'gs://pp003231/a4a.wav'
config = speech.types.RecognitionConfig(
    encoding=speech.enums.RecognitionConfig.AudioEncoding.LINEAR16,
    language_code='en-US',
    enable_speaker_diarization=True,
    diarization_speaker_count=2)
audio = speech.types.RecognitionAudio(uri=speech_file)
response = client.long_running_recognize(config, audio)
print response
result = response.results[-1]
print result

控制台上显示的输出是回溯(最近一次调用)：文件"a1.py"，第131行，在打印response.results AttributeError：‘操作’对象没有属性‘结果’

关于我做错了什么，你能分享你的专家意见吗？谢谢你的帮助。

Answer 1

对于这篇文章的作者来说太晚了。然而，张贴的解决方案在未来的人，因为我也有类似的问题。将结果=response.Resuls-1更改为response.result().结果-1，它将正常工作

Answer 2

你能访问你桶里的wav文件吗？还有，这就是整个代码？看来sample_rate_hertz和进口品不见了。这里有来自google示例的代码复制/粘贴，但我对其进行了编辑，使其只具有diarization功能。

#!/usr/bin/env python
"""Google Cloud Speech API sample that demonstrates enhanced models
and recognition metadata.
Example usage:
    python diarization.py
"""

import argparse
import io



def transcribe_file_with_diarization():
    """Transcribe the given audio file synchronously with diarization."""
    # [START speech_transcribe_diarization_beta]
    from google.cloud import speech_v1p1beta1 as speech
    client = speech.SpeechClient()



    audio = speech.types.RecognitionAudio(uri="gs://<YOUR_BUCKET/<YOUR_WAV_FILE>")

    config = speech.types.RecognitionConfig(
        encoding=speech.enums.RecognitionConfig.AudioEncoding.LINEAR16,
        sample_rate_hertz=8000,
        language_code='en-US',
        enable_speaker_diarization=True,
        diarization_speaker_count=2)

    print('Waiting for operation to complete...')
    response = client.recognize(config, audio)

    # The transcript within each result is separate and sequential per result.
    # However, the words list within an alternative includes all the words
    # from all the results thus far. Thus, to get all the words with speaker
    # tags, you only have to take the words list from the last result:
    result = response.results[-1]

    words_info = result.alternatives[0].words

    # Printing out the output:
    for word_info in words_info:
        print("word: '{}', speaker_tag: {}".format(word_info.word,
                                                   word_info.speaker_tag))
    # [END speech_transcribe_diarization_beta]



if __name__ == '__main__':

    transcribe_file_with_diarization()

要运行代码，只需将其命名为diarization.py并使用以下命令：

python diarization.py

此外，您还必须安装最新的google云语音库：

pip install --upgrade google-cloud-speech
