【CSharp】使用反射调用SpVoice实现播放文本

使用方法 SPVoic S = new SPVoic(); S.Rate = 0; S.SpeakSave("You have selected Microsoft Sam as the computer's default voice.", @"c:/1.wav"); S.Speak("You have selected Microsoft Sam as the computer's default voice.");

	 * S.SpeakSave("You have selected Microsoft Sam as the computer's default voice.", @"c:/1.wav");
	 * S.Speak("You have selected Microsoft Sam as the computer's default voice.");

试试其它关键字
　SpVoice　　播放文本　
同语言下
可能有用的
