    {

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

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

      // Create a PromptBuilder object and append a text string.
      PromptBuilder song = new PromptBuilder();
      song.AppendText("Say the name of the song you want to hear");

      // Speak the contents of the prompt asynchronously.
      synth.SpeakAsync(song);
