Sound game

Hello, i am looking forward to create a small game that helps the player to control a specific object by my voice For example the more i sceram the more the avatar jumps higher The idea is to start showing the player visual of the sound level I have 2 main elements here First one is level of voice Secound is to try to add letters by level to show the player that he needs to pronounce a specific letter if pronounced correctly For example First level the player should pronounce the letter B Then he should say BABA The kid if he say BA then he will have correct sign So we need to be sure that he say it 2 times. BABA Then he will go to level 2 In level 2 he should say BAD Then he will win. After that he will go to level 3 where he should say DAD We need also to show a graphics of the avatar where he will be able to show his mounth lipsing exactly as he pronoiunce the letters Please check the avatar i had created we need to do more work on it This game should work simply on web we need to activate mic and should be able to be viewed on iphone I dont need a complecated game here i just want it for trial
