What's it called?

I listen to books on CD all the time--an hour and a half a day, to and from work. It's funny to hear what the readers are familiar with and what they seem to have no knowledge of. Recently one reader used "riffled" when I thought it must have been "rifled" in print. Check it out from dictionary.com--

This morning the reader kept talking about Port Sed, and I know it was Port Said, which I know is Port Sai-eed. Jeez, I sure am my father's daughter. He had a real thing for grammar, pronunciation and accents. When I started sounding like a midwesterner (a pronounced twang, nasal at that) he chastized me and mocked me.
