Acoustic Cues of /ħ/ and /ʕ/ in Hourani Jordanian Arabic: Investigating Sociolinguistic Variation

Abstract

This paper examines the interaction between the coarticulatory effects of pharyngeals on adjacent vowels and the speakers’ age and gender in Hourani Jordanian Arabic. To this end, 28 participants were recorded reading a list of 24 words containing a pharyngeal sound (/ħ/ or /ʕ/) preceded (word-finally) or followed (word-initially) by a short or long vowel. A total of 1344 tokens were extracted and then analyzed in PRAAT. The first three formant frequencies (F1, F2, F3) of each vowel were manually measured at the midpoint. The measurements were then normalized using Nearey’s (1977) intrinsic formula to reduce the effect of physiological differences between male and female speakers. The findings of the study show no significant effects of age or gender on the production of the adjacent vowels word-initially or word-finally. This suggests that, unlike the case of pharyngealized sounds (e.g., Omari and Jaber (2019)), pharyngeal-to-vowel coarticulation is not affected by the sociolinguistic variables of age and gender.
