Variation in pre-nasal raising of TRAP in Australian English

Abstract

Phonetically raised and fronted realizations of pre-nasal TRAP are increasingly common in Australian English with previous research suggesting that greater raising may be associated with speakers from monolingual English-speaking backgrounds. Here, we present the results of an acoustic examination of pre-nasal TRAP raising (which we refer to as HAND) in a corpus of speech recordings from 183 adolescent speakers (aged 15–18) from five areas of Sydney that differ according to levels of linguistic diversity and the major heritage languages spoken (English-only, Arabic, Chinese, Indian, and Vietnamese). We extracted 1971 items containing the HAND vowel, along with 1807 items of pre-obstruent TRAP and 540 items of pre-obstruent DRESS. We calculated the degree of raising in HAND relative to pre-obstruent TRAP and DRESS through Euclidean Distance. The results show increased HAND raising in female speakers, although less raising is seen in the area with the highest proportion of Vietnamese language background speakers. Among male speakers the greatest incidence of raising is seen in the area with the lowest level of linguistic diversity (i.e., highest level of English-speaking background). These results suggest that HAND raising is associated with English-speaking backgrounds, but also that this is a change led by females.
