My little one started out as an Isabella, pronounced E-sa-bella, hard on the E.  I was going for a call name of E-sa (in Spanish the I (eye) is pronounced as an E). But when I was playing with her, it went from E-sa! E-sa-bell-a! to just plain ol' Bella to Bella-Boo 
 
 
But she's not confused ... I think she answers to anything in the general vicinity of her name
