Lego Voice Controlled Chore Board

My idea is for a voice activated Lego Chore Board.  I'm sure we are all familiar with Chore Boards but maybe you also have experienced someone else taking credit for your work.  This Chore Board would be programmed to recognize each participants individual voices to help prevent this.  Once a chore is completed the person would walk up to the board and press the button at the bottom.  They would then say their name, the day and what chore they performed.  The board would recognize the voice and activate the switch for that day and chore, changing it from black to the color registered to that voice.  In my picture you can see a example of how it can be laid out and a example of the rotating colors mechanism.  My example family has decided to take Sunday off as Family Day, to rest and relax before going back to work or school.  A bonus feature would be a scoreboard for prizes like choosing the Family night movie, or choosing that weeks Family night dinner.
