推荐答案

您绝对不能在Web应用程序中使用COM组件*客户端.如果您考虑Web应用程序的工作方式以及服务器和浏览器之间的分离，那么您会明白为什么会这样(您的代码在一台计算机上运行，​​标记和客户端脚本在完全不同的浏览器中运行一).

(*:好的，如果(i)您可以保证您的用户都将使用IE，并且(ii)您可以保证他们将拥有所需的组件，则是可能的已安装，并且(iii)他们将您的站点放置在受信任的区域"中，以便可以访问ActiveX控件.在公司局域网中，这是可能的.但是您最好让他们安装桌面应用程序.)

如果您实际上想要在Web客户端中进行语音合成，则应在Silverlight和.Net Framework中使用语音合成，否则，必须让用户安装COM组件，然后他们才能使用您的网站，这将使大多数

You absolutely cannot use a COM component* client-side in a web application. If you think about how a web application works and the separation between server and browser, you''ll understand why that is (your code is running on one machine, your markup and client-side script is running in a browser on a completely different one).

(*: Okay, it is possible if (i) you can guarantee your users will all be using IE, and (ii) you can guarantee they will have the component you want installed, and (iii) they put your site in Trusted Areas so it can access ActiveX controls. In a corporate LAN this may be possible. But then you might as well make them install your desktop app instead.)

If you actually want speech synthesis in a web client, you should use Silverlight and the speech synthesis in the .Net Framework, otherwise you will have to make your users install a COM component before they can use your site, and that will turn most of them away (particularly as it''s a virus risk).
