The letter ח is pronounced like خ and ע is just a normal a or i, depending on the vowel. In the old, original hebrew there were pronounced like the arabic letters, but in nowadays modern hebrew not anymore.Same as ק which originally was pronounced like arabic ق but now it's just a normal "k" sound. כּ is just "k" , without the point it is also like the arabic خ. Hope that helped שלום وسلام

Thanks Mark..actually these letters are pronounced like Arabic by Mizrahim (the Jews who came from Arabic-speaking countries) .....this site has helped me a lot :http://www.ulpan.net/hebrew-alphabet

Just to add some information. I've listened to a comparatively famous Tanach chanting record, in which the letter ח is read as ح in Arabic, and ר as ر , and ע as ع , and ק as ق. I've read articles saying that in the begining the standardization of modern Hebrew pronunciation is like what I heard in the chanting, but today, Isreali Hebrew has turned to the easier way.
