I'm a bit of a minimalist when it comes to dialogue tags and thus some of my speakers are often only differentiated by changing paragraphs and other grammatical techniques, which make it (hopefully) obvious to the reader who is speaking. Just wondering if it's the writer's responsibility to paint it black and white so that someone listening to it (audiobook, etc.) knows exactly what's going on?
Would it ever be expected that a writer make two versions of his novel? One for readers, one for audiobook?
I can just imagine some monotone grandfather reading my writing to his kid and confusing the s**t out of him.
