With Activoice... Works great! By default it is assigned a short home button hold to activate it. I found when using this default way it would usually open up google voice search and then a second later Siri would open on top of it. So I changed the settings in activator for to activate google voice search on a triple home press no matter the state your phone is in. Great to have google voice search for web stuff and Siri for reminders and appointments only now(which I find Siri is best at) Try it out!
