I like the first ten or so books of the Honor Harrington series by David Weber. I read them before I listened to them. It's interesting to me to hear the pronunciation of the reader after I've read the books. Manticoran is a case in point. When I was reading it, I thought it was pronounced like manticore with un on the end. The reader pronounced it man tic a run instead of man ti core un. So I got used to hearing it pronounced man tic' a run. It's pretty silly to think about it as it is a fictitious place. In A Rising Thunder, the reader pronounces it man ti core un.
I was reading a survivalist series where the reader pronounced cache as cash ay. On about the third book in the series somebody had convinced the reader that it is correctly pronounced cash.
