While using text to speech function in Windows XP, how to stop the speech in mid sentence?

I making a Windows Form app that uses the Speech SDK (SAPI 5.1) to do some text to speech functions. Here's the code I'm using.

using SpeechLib;
public SpVoice obSpeech = new SpVoice();
obSpeech.Speak("Some really long sentence", SpeechVoiceSpeakFlags.SVSFlagsAsync);

Now when I give a really long sentence, it continues speaking till it finishes the sentence. Is there any way to stop the speech in mid-sentence? What I mean is, when I press a button (say btnStop), can I make it stop speaking?
Please help.

Yup, this should do the trick:

C#

void Button1_Click(object sender, EventArgs e)
{
    obSpeech.Speak("", SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak);
}
