Add Options to Fine Tune Dialogue/Speech Mannerisms

There should be a way to edit the way a character speaks and acts while making a new character/editing one. For instance, add another option like the "Personality" options but for "Speech Mannerisms".

Let's say I have a character that is blunt and mean and curses a lot. I can add/edit that description of how they should talk/interact to their AI so that they act like that every time. There can also be an additional box for example sentences that the AI can analyze to act correctly. If I want a character to be mute, only speaking with gestures using asterisks, then I just write "mute, does not speak whatsoever, uses simple gestures to communicate, etc." in the speech description box (if that makes sense.)
