Abstract:
This study provides an acoustic investigation of the secondary articulation of Arabic emphatic sounds. The study observed seven male Arabic speakers from four dialects to investigate F1 and F2 of /a:/, /i:/ and /u:/ in emphatic and non-emphatic environments in 501 monosyllabic words. A repeated-measures ANOVA was conducted to examine the main and interaction effects of emphasis with consonant, vowel, and position factors. Regardless of the inter-subject variability, the Gaussian classifi- cation model shows limited differences among subjects. Index Terms: Arabic, dialect, emphatics, formants
