Fiona Bruce has 2 voices/accent. The one she uses to read the news is posh but other times its not.I had an auntie like that she changed it to suit who she was talking to !
I too like different accents it would be pretty boring if there was just one ! A customer of mine is from Belfast and what a strong accent that is.As I know him well I tell him, what was that you said John ? He laughs as he knows it is hard going. My favourite accents though are a Welsh female, and a soft Scottish female accent,and a Scandinavian female talking !
