# 使用 Amazon Polly 的代码示例 AWS SDKs
<a name="polly_code_examples"></a>

以下代码示例向您展示了如何将 Amazon Polly 与 AWS 软件开发套件 (SDK) 配合使用。

*操作*是大型程序的代码摘录，必须在上下文中运行。您可以通过操作了解如何调用单个服务函数，还可以通过函数相关场景的上下文查看操作。

*场景*是向您展示如何通过在一个服务中调用多个函数或与其他 AWS 服务服务结合来完成特定任务的代码示例。

 演示如何使用 Amazon Polly 和 Tkinter 创建口型同步应用程序，该应用程序显示正在说话的动画表情以及由 Amazon Polly 合成的语音。口型同步是通过向 Amazon Polly 申请与合成语音匹配的视素 (viseme) 列表来实现的。  
+ 从 Amazon Polly 获取语音元数据并将其显示在 Tkinter 应用程序中。
+ 从 Amazon Polly 获取合成语音音频和匹配的视素语音标记。
+ 在播放音频时，同步播放动画表情中的嘴部动作。
+ 提交异步合成任务以获取长文本，并从 Amazon Simple Storage Service (Amazon S3) 存储桶检索输出。

 此示例应用程序可分析并存储客户反馈卡。具体来说，它满足了纽约市一家虚构酒店的需求。酒店以实体意见卡的形式收集来自不同语种的客人的反馈。该反馈通过 Web 客户端上传到应用程序中。意见卡图片上传后，将执行以下步骤：  
+ 使用 Amazon Textract 从图片中提取文本。
+ Amazon Comprehend 确定所提取文本的情绪及其语言。
+ 使用 Amazon Translate 将所提取文本翻译为英语。
+ Amazon Polly 根据所提取文本合成音频文件。
 完整的应用程序可使用  AWS CDK 进行部署。有关源代码和部署说明，请参阅中的项目[ GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/ruby/cross_service_examples/feedback_sentiment_analyzer)。
