Upper Case voice
This is used when a person raises his or her voice or gives prominence to a part of a sentence to emphasize significance as you would while typing in the digital world, like email, chat, and instant messaging services. In novels, books, and textbooks, these words would actually be in italics. Upper Case voice is like italicized words or wording.
A Speech Therpist: These are a few ways to recite the same sentence with emphasis on a different word each time. Each emphasis gives the sentence a whole, new, and different meaning. Please repeat after me:
YOU are a son of a bitch.
you ARE a son of a bitch.
you are A son of a bitch.
you are a SON of a bitch.
you are a son OF a bitch.
you are a son of A bitch.
you are a son of a BITCH.
YOU ARE A SON OF A BITCH.
This is a derivative of Upper Case voice syndrome.

you are a son OF a bitch.
you are a son of A bitch.
