Definitely not a 100% perfect experience for me but it's been alright once in a while. I try it twice, if it doesn't work I just take out my phone and do what I want to do. I've found though that saying people's names as spelt (rather than as they are actually meant to be said) and enunciating (as everyone else mentions) works really well. It's a solid feature, hopefully it gets better. It's probably why Apple was never really interested in bringing Voice Control--because it's not as good as it should be. On another note, I did find out today that it requires a cell network connection to function (I was in the subway) -- I didn't realize this. On that note -- do people know if this is something that "learns" along the way or is it safe to say what we currently have is how it will always be until some software update?
