My idea for implementing voice command technology into LEGO models allows you to interact and control powered models easily by saying a colour coded to a specific command. This would be compatible with the Mindstorms, BOOST and Powered Up lines.
<font color="#000000">It also has a paired accessory in the form of a microphone (called the "MicolourPhone) with which the user can conventionally say the colours into. It likewise has a vibrant aesthetic look, as well as an attached plate for customising. Both devices are rechargeable, and they feature an LED which lights up when they're connected.
The colour coding is split into 3 different categories, all of which can operate together (See pages for more details) ->
I believe this colour-coordinated system will make for an easy and enjoyable experience when interacting with LEGO robotics. It can also be somewhat educational with some of the particular colours allocated to certain commands; for instance, the green, yellow and red colour colour codes for transport would be good for younger users especially so they learn more about traffic light safety.
I think you will be over the rainbow with this voice experience for LEGO robotics! =)
