#Emby Voice commands

Emby voice commands use json and regular expression to find corresponding commands.

With this solution the translation to other languages will be simplified and is fully compatible with regular expression for many programming languages.

###Json template :

[
	{
	"group": "general",
	"name": "General commands",
    "defaultValues": {
            "sourceid": "",
            "deviceid": "",

        },
	"items": [
