             VoiceObj = new ActiveXObject("Sapi.SpVoice");
         }
         catch (e) {
             VoiceObj = null;
         }
         function InitializeControls() {
             var VoicesToken = VoiceObj.GetVoices();
             var AudioOutputsToken = VoiceObj.GetAudioOutputs();
         }
         if (null != VoiceObj) {
             InitializeControls();
         }
         function SpeakText(strMsg) {
             try {
                 VoiceObj.Speak(strMsg, 1);

             }
             catch (exception) {
                 alert("Error");
             }
         }
         function myClose() {
             delete VoiceObj;
         }
         $(function () {
             var ab = "111111111112333333";
