Bride Groom Speech

If the bride and groom pay for their wedding, welcoming the guests?
I am paying for my wedding, but I was wondering – my father should make the first intervention welcome to the guests? I kind of want to do that because my dad is my guest as well. Would that be inappropriate?
Why not, guests nobody knows who is paying for the wedding they do? im sure her father expected her to make a speech.
