DotNetSpeech 可以生成Wave音频文件

using DotNetSpeech;
这样就实现了SAPI SDK的导入，下面我们就可以开始编写应用代码了。本示例演示如何把文本通过喇叭朗读出来以及把文本转化成语音信号（Wave声音文件），程序界面如图(3)：

//朗读
private void buttonSynthesis_Click(object sender, System.EventArgs e)
{
try
{
SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
SpVoice Voice = new SpVoice();
Voice.Speak(this.textBoxText.Text, SpFlags);
}
catch(Exception er)
{
MessageBox.Show("An Error Occured!","SpeechApp", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
//生成声音文件(Wav)
private void buttonTTStoWave_Click(object sender, System.EventArgs e)
{
try
{
SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
SpVoice Voice = new SpVoice();
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "All files (*.*)|*.*|wav files (*.wav)|*.wav";
sfd.Title = "Save to a wave file";
sfd.FilterIndex = 2;
sfd.RestoreDirectory = true;
if (sfd.ShowDialog()== DialogResult.OK)
{
SpeechStreamFileMode SpFileMode = SpeechStreamFileMode.SSFMCreateForWrite;
SpFileStream SpFileStream = new SpFileStream();
SpFileStream.Open(sfd.FileName, SpFileMode, false);
Voice.AudioOutputStream = SpFileStream;
Voice.Speak(txtSpeakText.Text, SpFlags);
Voice.WaitUntilDone(Timeout.Infinite);
SpFileStream.Close();
}
}
catch(Exception er)
{
MessageBox.Show("An Error Occured!","SpeechApp", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
