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：
public partial class frmMain : Form
{
public frmMain()
{
InitializeComponent();
comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
}
SpVoiceUtil SpVoiceUtil = new SpVoiceUtil();
private void frmMain_Load(object sender, EventArgs e)
{
Control.CheckForIllegalCrossThreadCalls = false;
List<string> list = SpVoiceUtil.getDescription();
foreach (var item in list)
{
comboBox1.Items.Add(item);
}
if (comboBox1.Items.Count > 0)
{
comboBox1.SelectedIndex = 0;
}
}
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
SpVoiceUtil.setDescription(this.Text);
}
//暂停
private void button2_Click(object sender, EventArgs e)
{
SpVoiceUtil.Pause();
}
//继续
private void button5_Click(object sender, EventArgs e)
{
SpVoiceUtil.Resume();
}
//停止
private void button3_Click(object sender, EventArgs e)
{
SpVoiceUtil.Stop();
}
//设置语速
private void trackBar1_Scroll(object sender, EventArgs e)
{
lab_Rate.Text = trackBar1.Value.ToString();
SpVoiceUtil.setRate(trackBar1.Value);
}
//设置音量
private void trackBar2_Scroll(object sender, EventArgs e)
{
lab_Volume.Text = trackBar2.Value.ToString();
SpVoiceUtil.setVolume(trackBar2.Value);
}
//开始朗读
private void button1_Click(object sender, EventArgs e)
{
SpVoiceUtil.Speak(txt_str.Text, CallBack);
}
//写出WAV
private void button4_Click(object sender, EventArgs e)
{
bool isTrue = false;
SaveFileDialog dialog = new SaveFileDialog();
dialog.Filter = "All files (*.*)|*.*|wav files (*.wav)|*.wav";
dialog.Title = "保存WAV文件";
dialog.FilterIndex = 2;
dialog.RestoreDirectory = true;
if (dialog.ShowDialog() == DialogResult.OK)
{
isTrue = SpVoiceUtil.WreiteToWAV(dialog.FileName, txt_str.Text, DotNetSpeech.SpeechAudioFormatType.SAFT11kHz16BitMono);
}
if (isTrue)
{
MessageBox.Show("输出成功");
}
else {

}
}
//回调信息
