6ayeb, here it is
the digits represent the sounds in arabic that do not have an equivalent in english, e.g. the 7 is a hard H from throat kinda thing, 5 is umm something between the 7 and the normal h, 3 is a sound similar to a, but more umm muffled in a way, the 2 represents something of a sharp 'stop' to a sound... the 9 is a an s and the 6 is a t that come from the throat ... am i missing any digits here lol... and im not arab, its probably best if rock star looks over these explanations, as im not good with explaining neither... btw there a few sites that offer audio samples of the letters/sounds, if you are interested let me know....
ah and i just remembered rock star had posted this in relations to the digits :
7 --> ح which is a sharp H from the throat
2 --> ء which is the gloatal stop, like when you say "Apple", it's the 1st sound
3 --> ع which sounds like gaging
and the link to whole thing is below, if you wanna go over it
