为什么谷歌语音输出只显示最后一个单词？

Question

我使用下面的代码来转录音频文件。当这个过程完成时，我只知道最后一句话。你知道吗

我已经尝试了flac和wav文件，并确保文件在我的桶。 同时验证了谷歌的服务帐户是否正常工作。但我不明白为什么我只能说最后一句话。你知道吗

def transcribe_file_with_diarization():
    """Transcribe the given audio file synchronously with diarization."""
    # [START speech_transcribe_diarization_beta]

    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()

运行代码后，结果如下所示：
