> To the best of my knowledge, there's no particular law that says a human brain is exempt from copyright, but it empirically is, because the alternative would be utterly unreasonable. Human brain most definitely is not exempt. If you read Lord of the Rings and then write down a new book, with the same characters and same story line - that's plain copying(lookup the etymology of the verb to copy). If you look at a painting and paint a very similar painting - that's still copying. Human brains are the reason we have copyright. Your recital of passages from any copyrighted book would violate the copyright, if not for fair use doctrine. And it has nothing to do with whether you do it yourself, or have a TTS engine produce the sound.
