Siham, how do you pronounce your name?
Well, I hope you prepared yourself for a headache.
I don't have any idea how my name can be pronounced in English as it is an Egyptian/Arabic name and the pronunciation in Arabic is even different from the one in French.
In Arabic and with the latin alphabet, my name is spelled Sihem - pronunced Si-rr-hem.
While in French, it is pronounced S-ee-h-am, there's no 'rr' sound, and the 'a' sound is the French one.
I hope it helps you.
