@coolbotic No it’s not very pretty :) I’ll see what I can do

Don’t know. I coded with it in python. To tell you the truth I have only heard of Electron about 10 minutes ago :) My magic mirror is coded in python (far more hacky and inelegant then your solution) but it entertained me for a while. :)

Hi
i haven’t put voice control into my mirror but have played around with it for a kitchen based recipe generator. (Say Baked Alaska and the display pulled a recipe off BBC food website and displayed it. )

Basically voice recognition is fairly simple. What is difficult is getting it to start listening.
The easiest way of doing it is to use the google api Here is a good source. http://stevenhickson.blogspot.co.uk/2013/06/voice-command-v30-for-raspberry-pi.html

The problem I had when I played with this is that. It records what you say and sends it to google for recognition. If you want a system that is always listening then you would end up sending recordings to google 24/7. . You could try using http://cmusphinx.sourceforge.net/ to recognize an initial key word then turn on google recognition. But I couldn’t really get a great response from that. However I have a strong Irish accent which doesn’t help :)
So you might have more luck. Also a good microphone will make your life easier.
