This paper describes the vowel system of Damascus
Arabic in Syria, from now onwards referred to as
Syrian Arabic (SA). We examine the acoustic
correlates of SA short/long vowel contrasts, and
investigate the status of mid vowels in SA. The goal is to expand on the auditory description of the SA vowel system performed by Cowell [8]. The full set of vowel categories proposed by Cowell were produced in a neutral /hVd/ context by fifteen SA speakers. Quantitative analysis of vowel duration and formant measurements confirms that the vowel system of Syrian Arabic includes the main /i(ː)/, /a(ː)/, and /u(ː)/ short/long vowel contrasts and supports the phonemic status of mid-long vowels /eː/ and /oː/. However, the phonemic status of the mid short vowels [e] and [o] and of schwa was not supported and they are analysed as allophonic variants of their high counterparts /i/ and /u/, respectively
