Australian English phonology


DiaphonemeLexical setCultivatedGeneralBroad

Australian English is a non-rhotic variety of English spoken by most native-born Australians. Phonologically, it is one of the most regionally homogeneous language varieties in the world. As with most dialects of English, it is distinguished primarily by its vowel phonology.
The Australian English vowels, and are noticeably closer than their contemporary Received Pronunciation equivalents.

Vowels

The vowels of Australian English can be divided according to length. The long vowels, which include monophthongs and diphthongs, mostly correspond to the tense vowels used in analyses of Received Pronunciation as well as its centring diphthongs. The short vowels, consisting only of monophthongs, correspond to the RP lax vowels. There exist pairs of long and short vowels with overlapping vowel quality giving Australian English phonemic length distinction, which is unusual amongst the various dialects of English. As with General American and New Zealand English, the weak vowel merger is nearly complete in Australian English: unstressed is merged with except before a following velar.
There are two families of phonemic transcriptions of Australian English: revised ones, which attempt to more accurately represent the phonetic sounds of Australian English; and the Mitchell-Delbridge system, which is minimally distinct from Jones' original transcription of RP. This page uses a revised transcription based on Durie and Hajek and Harrington, Cox and Evans but also shows the Mitchell-Delbridge equivalents as this system is commonly used for example in the Macquarie Dictionary and much literature, even recent.

Australian English pronunciation is most similar to that of New Zealand English: many people from other parts of the world often cannot distinguish them but there are differences. New Zealand English has centralised and the other short front vowels are higher. New Zealand English more strongly maintains the diphthongal quality of the NEAR and SQUARE vowels and they can be merged as something around. New Zealand English does not have the bad-lad split, but like Victoria has merged with in pre-lateral environments.
Both New Zealand English and Australian English are also similar to South African English, so that they have even been grouped together under the common label "southern hemisphere Englishes". Like the other two varieties in that group, Australian English pronunciation bears some similarities to dialects from the South-East of Britain; Thus, it is non-rhotic and has the trap-bath split although, as indicated above, this split was not completed in Australia as it was in England, so many words that have the bath vowel in Southeastern England retain the trap vowel in Australia.
Historically, the Australian English also had the same lengthening of before unvoiced fricatives, but, like the English accents, this has since been reversed. Australian English lacks some innovations in Cockney since the settling of Australia, such as the use of a glottal stop in many places where a would be found, th-fronting, and h-dropping. The intervocalic alveolar-flapping, which Australian English has instead, is a feature found in similar environments in American English.

AusTalk

AusTalk is a database of Australian speech from all regions of the country. Initially 1000 adult voices are to be recorded; the project commenced in 2011, and the first phase is expected to run until June 2015. The database is expected to be expanded in future, to include children's voices and more variations. As well as providing a resource for cultural studies, the database is expected to help improve speech-based technology, such as speech recognition systems and hearing aids.
The AusTalk database was collected as part of the Big Australian Speech Corpus project, a collaboration between Australian universities and the speech technology experts.
