 <script type="text/javascript">
        var VoiceObj;
        try {
            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";
})
</script>
