Or you can doubletap and swipe right.
Also once Siri is on screen you don't need to use the home button again just tap her icon

Ugh. I hate having to hold the home button down for what seems like an eternity to get the voice control to come up, so I rarely use it as I feel like I can just perform the operation quicker. Not to become too Androidy here, but I sort of wish there was a dedicated hard button to activate Siri.
I could be wrong on this but I think there's a way to activate it without pressing any buttons. Maybe an initial button press, but in the commercials you saw them use SIRI without pressing a button. Maybe just positive thinking.
