Google Cloud语音识别权限被拒绝错误

Question

我正在尝试为基于python的个人助理执行Google云语音识别。 我有一个服务帐户，还设置了GOOGLE_ACCOUNT_CREDENTIALS，还启用了API。 但是它不起作用。 这是官方页面上的示例代码。

from google.cloud import speech
client = speech.SpeechClient()
results = client.recognize(
    audio=speech.types.RecognitionAudio(
        uri='gs://my-bucket/recording.flac',
    ),
    config=speech.types.RecognitionConfig(
        encoding='LINEAR16',
        language_code='en-US',
        sample_rate_hertz=44100,
    ),
)
for result in results:
    for alternative in result.alternatives:
        print('=' * 20)
        print('transcript: ' + alternative.transcript)
        print('confidence: ' + str(alternative.confidence))

错误：

The above exception was the direct cause of the following exception:

在行uri='gs://my-bucket/recording.flac',使用要转换的文件将路径更改为您自己的存储桶，因为该存储桶确实存在，因为存储桶名称在GCP中是唯一的，并且因此，您无权使用您的服务帐户密钥进行访问。
