I think of my accent as old-line General American with an inkling of RP (e.g. I say “prIvacy” rather than “prAIvacy,” “SCHedule” instead of “sKedule,” “DArby” in place of “DErby,” and so forth — a remnant of being drilled in RP at school). “Old school” since it doesn’t have the valley-girly melodiousness of most current American accents. (I’m just making up the terminology on the go, but suffice it to say that there is an irritating singsong quality to the way most young Americans speak [think Matthew Yglesias] less common with their seniors.) I can also do a passable British toff impersonation (i.e. good enough to fool gullible Americans ) and — if I’m in a tight spot — ghetto-style, gunslinger American!
