The transcription of Hebrew letters
used on chayas.com (by Shemaryahu Esrael):

For the sake of simplicity and clarity, as well as accuracy, chayas.com originally based
its transcription of Hebrew characters on the system used in the Septuagint--
although we actually rely on the Masoratic text in our religion--this system was adopted.
Since Greek words are an integral part of the English language, the phonology
is familiar to readers world-wide. Also, the flexibility of Greek phonology allows us to
represent Yemenite pronunciations with a marked degree of accuracy. HOWEVER, 
this is an ongoing process which is not yet complete.  As I have received and incorporated
thousands of sniblits of material from readers and contributors, it is very difficult (probably
impossible) to impose this standard on everything that is contributed. On this site, you will
see everything from dictionary transliteration to homemade Temani transliteration.

I apologize in advance for the current level of nonconformity in this area. Although some would argue against
transliteration altogether, we think it is worthwhile for our English speakers. So please bare with us. 

The letters will be transcribed as follows (plosive/fricative):

Although Sin and Samawkh have slightly different sounds --we present them as the (same) English letter "s" below.
