In the project explorer, right click on references. Click on the COM tab. choose Microsoft Speech Object Library, then click ok.



Add the following code to your form:

  using SpeechLib;

and the btnRun_Click  event:

  private void btnRun_Click(object sender, EventArgs e)
        {
            SpVoiceClass v;
            v = new SpVoiceClass(); // create SpVoiceClass instant
            v.Rate = 1;// set rate as 1
            v.Speak(txtText.Text, SpeechVoiceSpeakFlags.SVSFlagsAsync); // text to speech
        }

Happy coding!
