GetSpeechSynthesisTask与 AWS SDK 或 CLI 配合使用

以下代码示例演示如何使用 GetSpeechSynthesisTask。

CLI

AWS CLI

获取有关语音合成任务的信息

以下 get-speech-synthesis-task 示例检索有关指定语音合成任务的信息。

aws polly get-speech-synthesis-task \
    --task-id 70b61c0f-57ce-4715-a247-cae8729dcce9

输出：

{
    "SynthesisTask": {
        "TaskId": "70b61c0f-57ce-4715-a247-cae8729dcce9",
        "TaskStatus": "completed",
        "OutputUri": "https://s3.us-west-2.amazonaws.com/my-s3-bucket/70b61c0f-57ce-4715-a247-cae8729dcce9.mp3",
        "CreationTime": 1603911042.689,
        "RequestCharacters": 1311,
        "OutputFormat": "mp3",
        "TextType": "text",
        "VoiceId": "Joanna"
    }
}
