This is my name and I've never liked it because it's painfully common. In all my classes there are always at least two Stéphanies and last year, I even had a teacher that was called like that too! The only thing that I like about it is its meaning (crowned). Still, I find it quite unintellectual and youthful; I can't picture myself when I'll be 80, still stuck with that name!
You also can pronounce it Stef-an-ee. Also I think it is a wonderful name as not too many people have it and it is just a really intriguing name! Also my sister is called Stephanie!
