    Tracking vowel categorization behaviour longitudinally: a study across three x three year increments (2012, 2015, 2018)

    Longitudinal data provide a unique opportunity to address questions around language change, and speaker/listener behaviour. Processing behaviour is considered subject to change over time, but it remains an open question as to over what time period incremental changes might occur. This study compares responses to a forced-choice listening test over three x three-year increments (2012, 2015, 2018), from a set of the same ten mainstream Australian English listeners. The listeners are from a small town (Warrnambool, Australia), where crucially, a distinction between /el/-/æl/ is lost for many. Here we focus on the contrasts between /ɪ e æ/ in /hVt/ and /CVL/ environments. Despite our predictions, overall results show that the increments, which span six years in total, are too small for any changes to arise. This study contributes to our understanding of longitudinal processing behaviour, showing overall consistency across 2012-2018, even in the context of a merger in-progress.

    Sociophonetic variablity of postvocalic /t/ in Aboriginal and mainstream Australian English
    Loakes, D ; McDougall, K ; Clothier, J ; Hajek, J ; Fletcher, J ; Epps, J ; Wolfe, J ; Smith, J ; Jones, C (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.

    Contemporary speech science is driven by the availability of large, diverse speech corpora. Such infrastructure underpins research and technological advances in various practical, socially beneficial and economically fruitful endeavours, from ASR to hearing prostheses. Unfortunately, speech corpora are not easy to come by because they are both expensive to collect and are not favoured by the usual funding sources as their collection per se does not fall under the classification of ‘research’. Nevertheless they provide the sine qua non for many avenues of research endeavour in speech science. The only publicly available Australian speech corpus is the 12-year-old Australian National Database of Spoken Language (ANDOSL) database (see http://andosl.anu.edu.au/; Millar, Dermody, Harrington, & Vonwillar, 1990), which is now outmoded due to its small number of participants, just a single recording session per speaker, low fidelity, audio-only rather than AV data, its lack of disordered speech, and limited coverage of indigenous and ethnocultural Australian English (AusE) variants. There are more up-to-date UK and US English language corpora, but these are mostly audio-only, and use of these for AusE purposes is not optimal, and results in inaccuracies.
