Production of Arabic Geminates by English Speakers.

This study investigates the production of Arabic intervocalic geminate obstruents as produced by American L2 learners of Arabic. The participants of the study were 24 Arabic learners (12 advanced, 12 beginners) at North Georgia University and 12 native speakers of Jordanian Arabic (the control group). An examination of the results reveals that native speakers of Arabic and advanced Arabic learners pattern similarly while the beginner Arabic learners show a different pattern. Native speakers as well as advanced L2 learners of Arabic maintain a contrast between geminate and singleton consonants in terms of consonant duration while beginner L2 leaners do not. Unlike the case of the beginner L2 learners, the duration of the preceding vowel is found to be shorter before a geminate in native speakers and advanced L2 learners. However, the duration of vowels following a geminate is not affected across all proficiency levels. Further, the results suggest that the place and manner of articulation have no effect on the production of geminate consonants for both native and advanced L2 learners. Finally, voicing of geminates is found to have a significant effect on the duration of geminates, in favor of voiceless geminates, among native speakers and beginner L2 learners.
