This is a lesson for reading practice. First, listen how the Aa "a"  vowel  combined with the consonants at the word level is spelled out and pronounced. Notice that A "á" vowel is sometimes read as a neutral vowel like in b"bá" of  bmasa"bâ ma za".  Also remember that the voiceless consonants like s"s" are liable to change to a voiced consonants at the word level.  For example see  s"s" change to   z"za" in the word  bmasa  "bâ ma za."
