    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.
