I need to ask you a question about His Dark Materials, I have also never read them but I have listened to an unabridged audio version. In the version I listened to the character's dialogue was acted by different actors (I don't remember anyone else but Joanna Wyatt was Lyra) and the voices definitely influenced the way I pictured the characters.
Is this the version you listened to? If so, did the different actor's voices affect your own visualisation of the characters? Do you think that your imagination would have had a freer reign if you had just read the books.
That was not the best example actually - because that sounds like the version I have. The voice of the Narrator is Pullman himself, which I love, but each time a character speaks inside quotation marks in the book those words are voiced by a different actor. This has two effects:
1) it definitely influences the picture you paint in your mind of the characters - which is good or bad, if the author is involved and approves the choices then I think it helps him get his story across better, but if not, then it is some random other person's vision that's influencing your mental picture, which is not so good!
2) I'm somewhat dyslexic, and I'm very bad with keeping names straight, but I never forget a voice, so, I find the different voices very helpful. I imagine that if you have no such troubles, this is 110% irrelevant to you.
My favourite audio books are read by a single reader. To me that's the best way to tell a story, which is what a fiction author is trying to achieve IMO. I simply adore Stephen Fry's reading of the Harry Potter series, and re-listen to it every few years. Mind you, I think I would enjoy listening to Fry read the phone book
I guess it all comes down to whether you think a book is a vehicle for transporting stories, or an end in itself. I see it as a vehicle, my parter and many others as an end in itself. The reason I like audio books are the very reasons he doesn't!
