推荐答案

然后我应该说您使用SpVoice，但您不知道它的功能.
可以同步或异步调用 SpVoice.Speak()方法.当被同步调用时，该方法直到说出文字后才返回；当异步调用时，它将立即返回，并且语音作为后台进程讲话.
因此，使用异步方法而不是同步方法，应该可以解决您的问题.像ase一样使用 SpeechVoiceSpeakFlags.SVSFlagsAsync .

Then i should say you use SpVoice,but you don''t know about it''s features.
SpVoice.Speak() method can be called synchronously or asynchronously. When called synchronously, the method does not return until the text has been spoken; when called asynchronously, it returns immediately, and the voice speaks as a background process.
So use asynchronous method instead of synchronous,your problem should be solved.Use SpeechVoiceSpeakFlags.SVSFlagsAsync as like ase..

SpVoice voice = new SpVoice ();
 voice.Speak ("An example of SpVoice.",SpeechVoiceSpeakFlags.SVSFlagsAsync);

下面的代码是我的项目之一的一部分...
我使用 System.Speech dll的 SpeechSynthesizer 类.
创建一个实例，如..

Below code is a part of one of my project...
I use SpeechSynthesizer class of System.Speech dll.
Create an instance like..

SpeechSynthesizer synthesis=new SpeechSynthesizer();

然后用于语音转换..

Then for speech conversion i use..

synthesis.SpeakAsync(richTextBox1.Text);//speaks the text

要停止讲话，我使用..

To stop speech i use..

synthesis.Dispose();//stops the synthesizer hence the speech!
