Hi,
I have previous experience with developing a voice controlled bot in Cortana. Developed 2 games in the bot framework and uploaded to Azure.
1. Millionaire Game: You can also check out the video for the same in my Portfolio. The game starts by reading out the rules and then starts asking questions with 4 option to each question. You also have 4 lifelines that you can use along the game progress.
2. Would you rather: It is a simple fun game where the user is asked a series of questions like "Would you rather eat a pizza or eat a burger". The user says out the word either pizza or burger and then cortana tells what percentage of people chose the same answer. It also plays back some sounds in between to encourage the player.
You will find me highly in sync of your requirements.
Thanks!
Swapnil
