Question

是否可以在基于javascript的通用Web应用程序中使用Cortana语音命令功能，该应用程序能够在任何webbrowser /平台上运行？（例如通过html5语音输入和某种类型的网络服务）或者网页是否必须在安装了Cortana客户端的基于Windows的计算机上加载？

我遇到了这个示例，但似乎期望在运行该页面的设备上安装Cortana： https://gist.github.com/seksenov/17032e9a6eb9c17f88b5

这是一个基本示例，您可以编辑为您的应用程序运行的代码： https://gist.github.com/seksenov/17032e9a6eb9c17f88b5
