exclamations and interrogations

Here we can see that Macduff is screaming a lot, and that when everybody talks is never to question, but to assert… Poor Macbeth and Lady Macduff question everything, while Lady Macbeth just as much as asserting.

Here we can see the variety of characters speech.

The brown-ish words are said just once per character. The light greens are word that will repeat on their speech, and the dark greens are repetitions of the light green words. I still need to take more measures to see if this is actually the way everybody speaks: by repeating a lot of small words with just some new words once in a while. (There are more words that appear just once, than the words you will repeat through most of your speech! Think about it!)
