There are different styles of emphasis: underlining, spacing, italics, bold face, all caps and small caps, change of font face, color etc. Some of them can be found in printed magazines, others have been in use in the past, yet others are common on the internet or in typewritten manuscripts. The question, which style of emphasis you might want to use is a question of _usage_: _What do publishers do, and what, therefore, do readers expect?_ If you go to a book store and flip through a shelf of recent publications, you will notice: **Most novels do not use emphasis at all!** Some novels use _italics_ for something like thoughts. And that's about it. Sometimes SF novels use other kinds of emphasis to mark brain-to-brain thought communication, computer voices etc. But no novel I remember reading uses any kind of emphasis to mark change in volume or intensity of speech.
