Phonologisation of vowel duration and nasalised /æ/ in Australian English

Research output: Contribution to journalConference paperResearchpeer-review

Abstract

An allophonic split in height between oral and nasalised /æ/ is an ongoing sound change in Australian English. Speakers participating in this change produce phonetically raised [ã] that overlaps the F1/F2 /e/ space, achieving [ã]/[ẽ] contrast through duration. We tested listeners’ sensitivity to this production change using forced-choice identification. Listeners responded to long and short synthetic /bVn/ and /bVd/ tokens constructed to simulate variation from /æ/ to /e/. Oral vowels were primarily identified according to F1 whereas listeners relied on length for nasalised vowels. This finding confirms the primacy of duration in cueing [ã]/[ẽ] contrast and indicates phonologisation of length.
