There are several Arabic letters which sound
quite similar to English speaking or other non Arabic speaking people.
There are particular ways the Arabs pronounce it which makes it sound
different from each other.
Al-Qari uses not only sounds of these letters to differentiate them from
each other but provides a graphic of the face cut and through animated
tongue teaches how each letter is pronounced.
The Al-Qari screen shot below compares the letter seen with letter sad
and sa. It describes them in text, compares them with sound, and shows
them with the animated tongue as compare button of each letter is clicked.
