Text to speech

i am devolping text to speech application in C#(windows Form Application).

i have done like :

SpVoice sp = new SpVoice();
sp.Speak(textBox1.Text, SpeechVoiceSpeakFlags.SVSFDefault);

but i need 2 types of voice for user to choose like
1.American voice
2.British voice

Any idea about how to do this..?
Thanking you.

Look at the GetVoices() method and Voice property on the SpVoice class here:
