Sociophonetic variablity of postvocalic /t/ in Aboriginal and mainstream Australian English

Abstract

This paper analyses post-vocalic /t/ variability in controlled speech across two groups, both L1 Aboriginal English and mainstream Australian English speakers. Data were collected in Warrnambool, a small community in western Victoria (Australia). While both Aboriginal English and mainstream Australian English speakers used canonical aspirated [tʰ] a range of other variants were observed.
