this could be very picky on mic sensitivity but it is pretty cool considering its a new way and idea to detect what words youre saying and for this you have to say huuut!!! or huut huuut!!! or hut huut huuuuuut and it has to be loud so like you have to be loud on the word until the end of the word not too long not to short because if its to quiet it wont pick up and detect the seconds and if the headset mic is to close it will mess up if its too far away it will mess up about pinky knuckle thats above the fingertip length away from your lip !! make sure of this or it wont work i will probably fix this up more and put it in the game project to replace the pick random thats in there for the calls and just detect how many times you call instead
