iOS 8 voice dialing, "Just to confirm..."
What a huge step backward in the usability of my iPhone. Instead of telling Siri, "call Mom mobile" and getting the response "calling Mom mobile" followed by the call going through, Siri now responds with, "Just to confirm, would you like to call Mom?". It may not sound like much but that extra step plus the required response from me makes it slower to use voice dialing than to remove the phone from my pocket and dial the number. Oh please let there be a way to switch this 'feature' off.
