using System.Threading;  

namespace SharedRecognizer  
{  
  class Program  
  {  
    static void Main(string[] args)  
    {  
      using (SpeechRecognizer recognizer = new SpeechRecognizer())  
      {  
        Grammar sampleGrammar = new Grammar(new GrammarBuilder("sample phrase"));  
        sampleGrammar.Name = "Sample Grammar";  
        recognizer.LoadGrammar(sampleGrammar);  

        OutputGrammarList(recognizer);  
      }  

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

    private static void OutputGrammarList(SpeechRecognizer recognizer)  
    {  
      List<Grammar> grammars = new List<Grammar>(recognizer.Grammars);  
      if (grammars.Count > 0)  
      {  
        Console.WriteLine("Loaded grammars:");  
        foreach (Grammar g in grammars)  
        {  
          Console.WriteLine("  Grammar: {0}",  
            (g.Name != null) ? g.Name : "<no name>");  
        }  
      }
