No Indoor Voice: Literature

  • In Dragon Bones, Ward adapted an inappropriately loud voice as part of his Obfuscating Stupidity.

  • Harry Potter has a lot of difficulty keeping his voice at a normal volume in Harry Potter and the Order of the Phoenix. Even when he's not in CAPSLOCK!Harry mode, you can make a drinking game out of the number of times Ron or Hermione indicate that he's getting unnecessarily loud for the situation. Semi-justified in that Harry appears to be suffering from a mild form of PTSD (and most likely puberty) and gets frustrated a lot.

    • In The Last Continent, it is mentioned that Archchancellor Ridcully "spoke as loudly as most people shouted."
    • While the voice of DEATH is also represented in Caps Lock, he's a subversion of this in the actual novels as it's mentioned that you "hear" DEATH inside your head, rather than with your ears. However, because that's just not possible in something with an audio component, audiobooks and movies of the books give DEATH the loudest and deepest voice they can possibly find, making him an actual example of this trope.
