用DotNetpeech.dll 可以朗读出文本，生成Wave格式的音频文件

首先要添加 dotNetSpeech.dll 文件的引用

 

实例化 spVoice voice=new dotNetSpeech.spVoice();

     spVoice 方法的 可以控制 文本朗读过程中的各个环节...

 

//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);

        }

}
