Google Cloud Speech API 无法在 Raspberry Pi 3 Raspbian OS 上的命令行

Question

我正在使用gcloud SDK在Raspberry Pi 3 Raspbian OS上测试Google Cloud Speech API命令行。谷歌提供的标准程序适用于我的Mac OSX！在 Raspbian 中尝试失败。

我尝试设置像"GOOGLE_APPLICATION_CREDENTIALS"和"GCLOUD_PROJECT"这样的 ENV var，当这不起作用时，我取消设置这些变量并尝试运行"gcloud beta init"而不是"gcloud init"。这些作品没有组合。

命令：

curl -v -k -s -H "Content-Type: application/json" -H "Authorization: Bearer `gcloud auth print-access-token`" "https://speech.googleapis.com/v1beta1/speech:syncrecognize" -d @sync-request.json

（注意：有关"sync-request.json"的内容，请参阅快速入门指南示例）。

我收到的错误消息如下所示。似乎错误的项目被选中了：

输出：

          }
        ]
      }
    ]
  }
}

Answer 1

通过在运行"gcloud auth"命令时指定"应用程序默认值"来解决身份验证问题（这意味着登录和打印访问令牌时）

首次运行：

gcloud auth application-default login

或者，您可以改为为服务帐户的private_key_id设置"GOOGLE_APPLICATION_CREDENTIALS"env var。

下次运行：

curl -v -k -s -H "Content-Type: application/json" -H "Authorization: Bearer `gcloud auth application-default print-access-token`" "https://speech.googleapis.com/v1beta1/speech:syncrecognize" -d @sync-request.json

您应该看到：

{
  "results": [
    {
      "alternatives": [
        {
          "transcript": "how old is the Brooklyn Bridge"
        }
      ]
    }
  ]
}
