应表哥要求，写一个简单的TTS软件，他们单位上用于广播通知用。源码如下：
简单说明：

foreach(variteminlist)
{
comboBox1.Items.Add(item);
}
if(comboBox1.Items.Count>0)
{
comboBox1.SelectedIndex=0;
}
}
privatevoidcomboBox1_SelectedIndexChanged(objectsender,EventArgse)
{
SpVoiceUtil.setDescription(this.Text);
}
//暂停
privatevoidbutton2_Click(objectsender,EventArgse)
{
SpVoiceUtil.Pause();
}
//继续
privatevoidbutton5_Click(objectsender,EventArgse)
{
SpVoiceUtil.Resume();
}
//停止
privatevoidbutton3_Click(objectsender,EventArgse)
{
SpVoiceUtil.Stop();
}
//设置语速
privatevoidtrackBar1_Scroll(objectsender,EventArgse)
{

}
//设置音量

SpVoiceUtil.setVolume(trackBar2.Value);
}
//开始朗读
privatevoidbutton1_Click(objectsender,EventArgse)
