There are interesting voice recognition uses, speech to text, search, etc... but for games it's been trying to replace button actions, right in line with shake the controller, or lean your whole body to turn, or shout "pew pew" to shoot your gun.
All of these games would be ridiculously easy if they were to also support button inputs (choice? right?). They have to gimp the game until it's playable with seconds of lag and must be forgiving of misunderstood commands. If they want to add voice commands, it better improve the game, and I haven't seen that yet after over 10 years of gimmick uses (dreamcast, gamecube, eyetoy, kinect).
