In my story, I have two books. One is Cthulhu Mythos and the other is The Little Prince. There is one scene that the protagonist is reading this two books to his daughter. And for Cthulhu Mythos, I search for the first chapter of it and copy them into the Markov Generator. The result it comes out that can not be understand is pretty conform to the impression of this book.
For the other story, which is The little Prince. I think when the protagonist is reading this book, he is really calm and with love. So I use Otter.ai to record me reading two paragraph of the story. It seems fit the story that "I" am reading the book.
