all caps to make the next word all uppercaseFor example, saying:

all caps on … all caps off to make part of what you say uppercaseFor example, saying:
I am hungry all caps on feed me now all caps off pleaseproduces the text:
I am hungry FEED ME NOW please
no caps to make the next word lowercaseFor example, saying:
I like no caps Mikeproduces the text:
