Individual variation in the frication of voiceless plosives in Australian English: A study of twins' speech

Abstract

This study is an acoustic-phonetic examination of variation in Australian English consonant production. Group and individual patterns in the rates of frication of the voiceless plosives /p t k/ in Australian English are investigated. Previous studies on voiceless plosive production in Australian English have focussed primarily on /t/, and these analyses have largely been auditory in nature. Further, whereas previous studies have focussed on describing sociophonetic variation within Australian English, this study investigates speaker-specific variation. An analysis of twin speech, produced by young adult male speakers from Melbourne, is presented. The speakers are three identical twin pairs a..
