No matter how much I browse, I cannot find any true researcher's really precise and accurate data on the issue. Actually, I cannot find any Gulf Arabic Phonology compendium, so any help will be greatly appreciated. Thanks in advance.
if you learn Arabic you will be able to adapt to any of the Arabic dialects, all Arabic dialect use the same Phonology with some minor exception like some letter imported from other languages mostly the sound
g rather than
j(ج) or ق, or switching some letter like
a(أ) rather than
ق. so i recommend you to learn Arabic.
