精灵讲话问题

Question

我想让 精灵发出真正的声音,已经下载了text_to_speech引擎和微软运行时发音的api4.0a,请问怎样去执行呢?
switch(name)
{
case "Genie": this.axAgent1.Characters.Load("Genie",(object)"GENIE.ACS");
myagent = this.axAgent1.Characters["Genie"];
break;
case "Merlin": this.axAgent1.Characters.Load("Merlin",(object)"Merlin.ACS");
myagent = this.axAgent1.Characters["Merlin"];
break;
case "Robby": this.axAgent1.Characters.Load("Robby",(object)"Robby.ACS");
   myagent = this.axAgent1.Characters["Robby"];
break;
case "Peedy": this.axAgent1.Characters.Load("Peedy",(object)"Peedy.ACS");
myagent = this.axAgent1.Characters["Peedy"];
break;
}
myagent.Show(null);
myagent.Think("谁明天生日？");
System.Threading.Thread.Sleep(8000);
this.myagent.Speak("噢，是的！",null);
请问怎样加载声音呢?
