Here I’m about to explain Text to Speech feature of C#. This simple example will demonstrate how to use Text to Speech feature of C#.

Example

                            Form Design

Code

Namespace for voice

using SpeechLib;

namespace TextTospeech

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        private void btnSpeak_Click(object sender, EventArgs e)

        {

//creating instance of voice

            SpVoice v = new SpVoice();

//Setting Rate of voice

            v.Rate = 2;

//calling speak() method of SpVoice class.

            v.Speak(rtxtSpeech.Text, SpeechVoiceSpeakFlags.SVSFPurgeBeforeSpeak);

        }

    }

}
