Voice Activated Scoreboard

I am developing a scoreboard app that keeps track of the score for 2 teams. The app will be horizonal and the numbers will take up the whole screen. The only other feature for the scoreboard part is being able to change the color of the background for each team. The one challenge for the project is that I am trying to have it voice activated where people can change the score by talking to the app. I have researched that siri can be integrated into apps and that might be able to work for my problem. The voice activated should be able to change the score and reset the score to zero.
