Abstract
This study is about the differences in articulations between men and women in Libyan Arabic from Tripoli and the social power structure of these differences. The corpus used is a list of words with consonants having strong distinctive values to a social point of view between men and women, i.e., pharyngealized consonants / s ˁ, t ˁ, d ˁ/and nonpharyngealized consonants /s, t, d/. Gender differences will be treated here through values of frequencyof the tow first formants [F1, F2] of the vowels /i, u, a/ which are linked to the pharyngealized and nonpharyngealized consonants. The results show significant differences between men and women and these differences are caused by social distinctions
