问题描述
我正在使用asp和c#创建一个聊天机器人Web应用程序.我在使用SpeechLib使用文本转语音"时遇到了一些麻烦，在页面加载后，它会先说出单词，然后再将其放入文本框，但应该先是文本框然后再说.
我认为脚本管理器存在冲突，但不太确定，谁能帮助我..我的代码是:
c#代码(default.cs)
I''m creating a chatbot web application using asp and c#. I am having a little trouble using Text-to-speech using SpeechLib, after the page loads, it speaks out the word before putting it to the textbox, but it should be textbox first then speak.
I think the conflict is on the scriptmanager, but not quite sure, can anyone please help me.. my codes are:

推荐答案
SpVoice voice = new SpVoice();
voice.Speak(text，SpeechVoiceSpeakFlags.SVSFDefault);
它在您的服务器上运行，而不是在客户端上运行.因此，它只能在提供您的页面之前运行.但是，您的客户端将永远不会听到它. ASP.NET不能做您想做的事，您需要嵌入一个客户端控件来做它.
SpVoice voice = new SpVoice();
voice.Speak(text, SpeechVoiceSpeakFlags.SVSFDefault);
This runs on your server, not your client. It can only run BEFORE your page is served, for that reason, but your client will never hear it. ASP.NET can''t do what you want, you need to embed a client side control to do it.
我知道这是一个老问题，但是无论如何这是一个答案.
这是来自Microsoft的演示SimpleTTS.html.它仅在iExplorer中运行，您必须在工具"，"Internet选项"，安全性"下启用activeX.
视位素图像仅仅是根据视位素变化事件选择的小嘴图像，以使其看起来像嘴巴在说话.据我所知，Microsoft在MSDN上不再有此代码.太糟糕了.
您可以按摩它以完成您想做的事情.祝你好运.
I realize this is an old question but here is an answer anyway.
This is from Microsoft and is their demo SimpleTTS.html It only runs in iExplorer and you will have to enable activeX under Tools, Internet options, Security.
The viseme images are simply little mouth images selected according to the viseme change events to make it look like the mouth is talking. Microsoft no longer has this code on MSDN as far as I can tell. Tooo bad.
You can massage this to do what you want it to do. Good luck.
