Well, I don’t exactly do a different accent, but I do tend to fall into the rhythms, patterns, and intonation of the people I am around. I also will pick up their idiosyncratic phrases and use them in conversation with them. So to my ears I sound like a completely different person depending on who I am talking to. And then I wonder if they are doing the same thing to some extent, and if we are all doing it, then what do we sound like in the absence of other people? What is our authentic sound? Do we even have one?
