using System.Speech.Synthesis;  

namespace SampleSynthesis  
{  
  class Program  
  {  

    static void Main(string[] args)  
    {  

      // Initialize a new instance of the SpeechSynthesizer.  
      using (SpeechSynthesizer synth = new SpeechSynthesizer())  
      {  

        // Configure the audio output.   
        synth.SetOutputToDefaultAudioDevice();  

        // Subscribe to StateChanged event.  
        synth.StateChanged += new EventHandler<StateChangedEventArgs>(synth_StateChanged);  

        // Subscribe to the SpeakProgress event.  
        synth.SpeakProgress += new EventHandler<SpeakProgressEventArgs>(synth_SpeakProgress);  

        // Speak the prompt.  
        synth.Speak("What is your favorite color?");  

        // Pause the SpeechSynthesizer object.  
        synth.Pause();  

        // Resume the SpeechSynthesizer object.  
        synth.Resume();  
      }  

      Console.WriteLine("\nPress any key to exit...");  
      Console.ReadKey();  
    }  

    // Write the state of the SpeechSynthesizer to the console.  
    static void synth_StateChanged(object sender, StateChangedEventArgs e)  
    {  
      Console.WriteLine("State: {0}    Previous State: {1}\n", e.State, e.PreviousState);  
    }  

    // Write the speak progress of the SpeechSynthesizer to the console.  
    static void synth_SpeakProgress(object sender, SpeakProgressEventArgs e)

    }  
  }  
}
