This game was really enjoyable! I haven't seen speech detection implemented like this in a game before. My only suggestion is you could have an in-game setting to change your Input Device, instead of having to go to the sound control panel to check my Default mic. Other than that, this was great! The game has some leniency to account for the speech loading times and it was fun to play. Looking forward as to how this concept can be developed.
