There are as many ways to say my name as there are languages with a concept of the number 4, or 44 if you'd prefer. You can use any of these you feel comfortable with- some of 'em are really fun to say.
Japanese: I-shi-shi or I-shi-ju-shi
German: E-vier-vier or E-vier-und-vier-zig
Swahili: E-nne-nne or E-a-ro-bai-na-nne
And a personal favorite:
Maori: E-e-whā-e-whā, or E-whā-teh-kau-mah-whā
You could get even more crafty with it and try translating "double four" too, but I think I've already given a fair enough place to start.
I just say 'E-four-four.'
