所以基本上我使用了两个语音识别引擎（speechrecog＆amp; speechrecog1）和一个语音合成器。当语音识别被问到一个问题，比如你是怎么回事 然后它回复我很好（如果计算机从两个数字1,2中选择2）。然后它初始化第二个语音识别引擎。什么时候做它的东西。然后关闭第二个，再打开第一个。但问题是当使用第二个语音识别引擎时，它重复（语音合成器）我尝试第二个语音识别引擎的次数。 这是我的代码：

例如： 文本文件you.txt如何包含： 我很好。谢谢。％你好＃好＃坏 并且计算机询问我是否良好并且我回复良好。在good.txt文件中： 哦，那太酷了
我第一次问她：你好吗？
回复：我很好。你好吗
用户：好
回复：哦，那很酷（1次）
我第二次问她：你好吗？
回复：我很好。你好吗
用户：好
回复：哦，那很酷（重复2次）
我第三次问她：你好吗？
回复：我很好。你好吗
用户：好
回复：哦，那很酷（重复3次）
如何解决重复问题。
答案 0 :(得分：0)
感谢@Nikolay Shmyrev我找到了解决方案。正如他所说，我的事件处理程序是两次开火。所以在里面我放了一个：
try
{
//My code
}
finally
{
speechrecog1.SpeechRecognized -= speechrecog1_SpeechRecognized;
}
