利用Cloudflare Workers实现免费搭建微软文字转语音服务
说明：目前网络上，文字转语音的软件众多，有免费的，也有收费的，但这些都依赖于他们的服务器需要维护，今天分享的教程，无需服务器，只需要将代码上传到Cloudflare Workers中，即可实现文字转语音服务。
项目介绍
此项目是基于微软azure的文本转语音服务，通过调用微软azure的api接口，将文本转换为语音，然后下载到本地。
教程开始
1. 访问 [button color="warning" icon="glyphicon glyphicon-cloud" url="https://www.cloudflare.com"]Cloudflare[/button]
2. 点击Workers 和 Pages，选择 创建应用程序 如下图
3. 点击创建Workers
4. 设置项目名称 注：名称会当作域名前缀
5. 复制代码 粘贴到如图所示位置 访问生成的域名即可
[scode type="yellow"]由于众所周知的原因，自动分配的域名基本无法访问，请继续往下查看教程！[/scode]
