Voice commands have been in Android for a long time (2.2?). They're not quite as smart as Siri (natural language processing, witty responses), though in my personal experience far more accurate (maybe that's because my phone has been trained to my voice over time and when I've seen Siri in action it's usually someone who just got the 4S).
