Wow there are some childish people on this forum, what does this add to the discussion? Are you taking the fact i'm having an issue with an apple product personally? This is mind blowing.
Sorry, buddy. You made the error of using the "A" word. That tends to prompt infantile responses from some posters.
Don't have the new iPhone and the iPad doesn't have Siri. I have, however, had experience with voice commands in that (unnamed) other environment. I suspect that you (and others) may be experiencing (a) the effects of massive server load, something that is very difficult to simulate in QA testing and/or (b) quality issues with your data transmission service.
Not much you can do about the former until things quiet down on the new toy front but you might try using Siri from various locations to see if better quality transmission of your voice makes a difference.
P.S. And if you're from SoCal, you certainly have an accent; everyone does. But it's an accent that Apple has certainly accommodated in Siri or it would never have made it out of NorCal.
