ItemThe secondary roles of amplitude and F0 in the perception of word-initial geminates in Kelantan Malay(Australasian Speech Science and Technology Australia (ASSTA), 2019)This study examines the extent to which amplitude and F0 play secondary roles in perceptually cueing the word-initial singleton/geminate consonant contrast in Kelantan Malay (KM). Three voiceless stop word-pairs produced in isolation, i.e. utterance-initial position, were chosen for manipulation in three perception experiments involving KM native listeners. Results show that amplitude and F0 have limited perceptual functions on their own, although the combined values of the two parameters do have some effect on the perception of the consonant contrast. These results are expected for the utterance-initial voiceless stop pairs given the absence of closure duration information as a perceptual cue in this context. The findings support the view that the consonant length distinction in word-initial position, particularly for voiceless stops, can be potentially cued by a set of secondary parameters, e.g. amplitude and F0, alongside the primary acoustic parameter of closure duration.

ItemSociophonetic variablity of postvocalic /t/ in Aboriginal and mainstream Australian English(ASSTA, 2018)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. The Aboriginal English group used a greater number of variants overall, and tended toward “glottal” variants (full glottal stops, pre-glottalised stops, and ejective-like stops) whereas the mainstream Australian group preferred so-called “breathy” variants (affricates, fricatives); we attribute this to sociophonetic variability, potentially linked with voice quality and glottal timing. Overall, the study highlights some previously undocumented variation both within L1 Aboriginal English, and between L1 Aboriginal English and mainstream Australian English.

ItemProsodic effects on vowel spectra in three Australian languages(International Speech Communications Association, 2014)In this paper, the spectral properties of vowels in three Australian languages are examined with the aim of determining whether prosodic prominence and domain-edge effects on formant frequencies, formant variability and vowel space dispersion can be identified. It is shown that these vowel systems are sufficiently dispersed, with an anchoring of the system by the open central vowel. It is also shown that for Burarra but not for Gupapuyngu or Warlpiri there is some evidence of prosodically-driven hyper-articulation. Finally, the data indicate pre-boundary lengthening in all three languages, which in some cases appears to be associated with changes in vowel quality.
