Take a look at my NavigationBar Module:
There’s a code-block like: “On click, toggle hide/show”. With the VoiceModule from alexyak u just have to change the onClick to socketNotificationReceived. Take a look at the dev instrucionts for MM: https://github.com/MichMich/MagicMirror/tree/master/modules#socketnotificationreceived-functionnotification-payload
So i would say:
First install the voice modul and configure it. Go on the Page and get some voice models and put in on your Mirror like it’s said in the voice module instruction. Then u can open the Mirror in Chrome or Firefox and open the console. Now just try the voice commands. In ur console should appear the voice commands.
Then the next step is to execute something on the incoming the notification. That’s the part, where i could help u to program ist.
