Abstract

Pharyngealisation is one of the most widely investigated phonetic phenomena in

Arabic. Pharyngealized consonants have an effect on the production of both vowels and

consonants in their vicinity. Despite the mystery surrounding this interesting phenomenon,

little is known about how it is employed by speakers of different dialects, especially in

Saudia Arabia. This study is intended to fill this gap by studying whether speakers of Hejazi

and Asiri dialects would differ phonetically with regard to the effect that the sounds /t/ and

/s/ vs. their emphatic counterparts /t?/ and /s?/ would have on the second formant (F2) of the

vowel in their vicinity. Two female speakers of each dialect were recorded producing

twelve words containing /t/ and /s/ vs. their emphatic counterparts /t?/ and /s?/. These

recordings were analyzed using PRAAT software to investigate the behaviour of the F2 of

the vowel in both dialects. Results show that the two dialects differ with respect to the

influence of the pharyngealized consonants on F2. While in Hejazi dialect, the lowering of

F2 in the vicinity of emphatic consonants was not significant compared to F2 in the vicinity

of their plain /t/ and /s/, in the case of Asiri dialect there was a significant lowering in F2.

This indicates that pharyngealisation does not have the same effect on F2 in all dialects but

differs in degree depending on the particular dialect.
