There are approximately 2 million Gulf Arabic speakers in Saudi Arabia, and the dialect is only spoken in the Eastern Province. The remaining Arabic speakers in the province speak one of the other two dialects, more commonly the Najdi dialect. Saudi Sign Language is the principal language of the deaf community. The large expatriate communities also speak their own languages, the most numerous of which are Indian languages, Filipino/Tagalog, Egyptian Arabic, Indonesian, Rohingya, and Urdu.Saudi Aramco, the state-owned oil producing company of Saudi Arabia, is based in Dhahran, which is located in the Eastern Province, and most decisions on oil policy and production that affect the global economy are made there. The kingdom's main oil and gas fields are mostly located in the Eastern Province, onshore and offshore. Notable among these are the Ghawar Field and the largest crude increment in the world. Petroleum from the fields is shipped to dozens of countries from the oil port of Ras Tanura and is also used as feedstock in numerous industrial plants in Jubail.
Arabic phonology
Even in the most formal of conventions, pronunciation depends upon a speaker's background. Nevertheless, the number and phonetic character of most of the 28 consonants has a broad degree of regularity among Arabic-speaking regions. Note that Arabic is particularly rich in uvular, pharyngeal, and pharyngealized ("emphatic") sounds. The emphatic coronals (, , , and ) cause assimilation of emphasis to adjacent non-emphatic coronal consonants. The phonemes ⟨پ⟩ and ⟨ڤ⟩ (not used by all speakers) are not considered to be part of the phonemic inventory, as they exist only in foreign words and they can be pronounced as ⟨ب⟩ and ⟨ف⟩ respectively depending on the speaker.. The standard pronunciation of ⟨ج⟩ varies regionally, most prominently in the Arabian Peninsula, parts of the Levant, Iraq, northern Algeria and Sudan, it is also considered as the predominant pronunciation of Literary Arabic outside the Arab world, in most of Northwest Africa and the Levant, and only in Egypt.
