Simple, Bibi!
But joking aside, here is one difference of German and English spelling at work, in English "Bibi" would be spelled "Beebee", like the "bi" in "bizarre", since for some reason English "e" is spelled like the German "i".
And German is normally spelled as written, there are few diphtongs or stuff you have to know (like "v" is "f" in all Germanic and very old loanwords, "v" is "w" in newer loanwords) and there are no silent end letters in German, so words/names like Porsche are spelled with a Schwa, a lowered, halfswallowed e, never silent.
