Writing for audio

Someone I know just signed a contract for one of her books to "go audio"--- be turned into an audiobook. That got me wondering if we should think about audio when writing or revising.  Does anyone else listen to auidobooks?

I read terribly aloud-- I mean, embarrassingly so. So I try never to do a
reading and will resist it to the end.

However, I'm an audible.com subscriber, and I think I've learned a few
things from listening to a few hundred audiobooks.

First, if you ever hope to "go audio," don't tag every line of dialogue.
Every other line will do and will sound better.

Also, if you sell to audio, provide a pronunciation guide for any
non-normal word. The reader won't be offended.

Other tips? Shorter sentences?
