Abstract
The current study investigates vowel durations of Arabic- speaking Broca’s aphasics. Three subjects diagnosed with Broca’s aphasia and three normal speakers participated in this study. Vowel durations of the short Arabic vowels (/i/, /a/, /u/) preceding voiced and voiceless fricatives were measured and analyzed. The effects of voicing on vowel duration are also investigated. The results show that the normal speakers as well as Broca’s aphasics complied with the phonological rule, vowels being longer preceding voiced fricatives. It is also demonstrated that vowel durations were significantly greater for Broca’s aphasics compared to normal speakers. Finally, this study is brought to bear on several aspects concerning timing and prosodic impairments of Broca’s aphasic speech. The finding may also have clinical applications concerning speech and language therapy in Palestine.
