possibly nick-names or last names etc.
for example
first name: "Hieronymus"
last name: "Lex"
nick-name: "Annoying Watch Captain"
you could switch the nickname around so it would be
Annoying Watch Captain Hieronymus Lex
or
Hieronymus Annoying Watch Captain Lex
or
Hieronymus Lex Annoying Watch Captain
of course, you dont have to fill in all of them, some people would just call you by your first name (if you filled that one in), or your nickname (if you filled that one in) or your last name (if you filled that one in)
you could choose what to have people call you
example:
"Hey, are you Mere-Glim"
"Yes, I am, but please, just call me Glim"
there could be titles, as well, and people would use that with your last/first name, or just the title
"Captain Hieronymus"
"Captain Lex"
"Captain"
now, i know TES traditionally doesnt use names, most just know you as "The Nameless Stranger," but, it is possible that someone would
at least know your first name
beth could use what http://www.xtranormal.com/ did to make movies
with xtra-normal (im not advertising, im explaining) youd simply type something in and the actor would [try to] pronounce it. it doesnt matter if you typed in "supercalifragilisticexpialidocious," it would still make an attempt to pronounce it
EDIT: spelled "supercalifragilisticexpialidocious" wrong
