            GrammarBuilder gb = new GrammarBuilder();
            gb.Append(colors);


            // Create the actual Grammar instance, and then load it into the speech recognizer.
            Grammar g = new Grammar(gb);
            sr.LoadGrammar(g);


            // Register a handler for the SpeechRecognized event.
            sr.SpeechRecognized += new EventHandler(sr_SpeechRecognized);
        }


        // Simple handler for the SpeechRecognized event.
        private void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {

                _serialPort.PortName = "COM3";
                _serialPort.Open();
                _serialPort.Write("#27 P1600 S750\r");

                string output;
                output = "";

                while (!(output == ".")) //loop until you get back a period 
                {
                    _serialPort.Write("Q  \r");
                    output = _serialPort.ReadExisting();
                    Console.WriteLine(output);
                    Thread.Sleep(10);
                }
                _serialPort.Close();
