This paper reports on an acoustic phonetic study of the VC rhyme in two Australian English dialects. The aim is to examine the timing features of the rhyme to determine the extent to which characteristics of Arabic predict differences between the two dialects. Eight speakers of Standard Australian English and seven of Lebanese Australian English were recorded using a standard word list task. Results show significant dialect specific timing differences which are dependent on vowel quantity and coda voicing. The results suggest that Lebanese Arabic prosodic constraints may have become ethnolinguistically functionalised in this new AusE dialect.
