In french "moi" sound like a "short flat sound" just -m' oi - (in english sound like inside whouah if exist )
Better if you ear it like "moy" more exotic sound for a frenchy exactly like in the english word "toy" :)
The only french word with this same sound is monoi (vegetal oil from Tahiti :)

But when a frenchy read moi he can't ear moi !)
So only the world celebrity will be make that :)
I make publicity for that ! Moy moy moy :)

Seems I can't write the i "dieresis" in the system of forum :(
so I had writed Moy for the sound :)
