“…There are various motivations for an investigation of this kind: first, a qualitative distinction would parallel relatively recent findings on qualitative differences in contrastive vowel length in Arabic (Alghamdi, 1998;Al-Tamimi, 2007); these have only been particularly noted since experimental work on Arabic vowels started to emerge, with previous small-scale studies suggesting that the contrast is purely durational (e.g., Al-Ani, 1970, among others). Second, while the phonology of Arabic is heavily oriented towards phonological contrasts in vowels and consonants that are based on length and moraic timing (e.g., Broselow et al, 1997;Davis, 2011;Watson, 2007), it is important to examine the phonetic basis of phonological length in order to test whether articulatory strength still plays a role in a contrast that is heavily based on phonetic timing. This would highlight the correlation between the two and enable the study of perceptual cues that might enhance this contrast.…”
