Hejazi Arabic
Hejazi Arabic or Hijazi Arabic ( '), also known as West Arabian Arabic, is a variety of Arabic spoken in the Hejaz region in Saudi Arabia. Strictly speaking, there are two main groups of dialects spoken in the Hejaz region, one by the urban population, originally spoken in the major cities of Jeddah, Mecca and Medina, and another by the Bedouin or rural populations. However, the term most often applies to the urban variety which is discussed in this article.
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.
