Rising Intonation in Australian English. The project will model the intonation of Australian English through an analysis of spoken dialogues from over 200 speakers. The study of the different types of rising intonation across different population groups will advance our knowledge of how Australian English is different from other accents, how it has changed in the last 40 years, and how accent is related to social class in Australia. The outcomes include publications on the theory of intonation, ....Rising Intonation in Australian English.

The study of the different types of rising intonation across different population groups will advance our knowledge of how Australian English is different from other accents, how it has changed in the last 40 years, and how accent is related to social class in Australia. The outcomes include publications on the theory of intonation, accent change, and its relationship to social class as well as a working model of intonation that can be implemented in a system for synthesising Australian English speech.Read moreRead less
The effects of sentence structure on consonant and vowel articulations. Whilst machine-generated speech is generally of good quality at the level of the single word, it is noticeably less natural-sounding at the level of the sentence. This project examines an important aspect of the naturalness of human speech, namely, the effect that sentence structure has on individual consonants and vowels. A break-down of this naturalness is seen in some speakers who have suffered traumatic brain injury: suc ....The effects of sentence structure on consonant and vowel articulations. Whilst machine-generated speech is generally of good quality at the level of the single word, it is noticeably less natural-sounding at the level of the sentence. This project examines an important aspect of the naturalness of human speech, namely, the effect that sentence structure has on individual consonants and vowels. A break-down of this naturalness is seen in some speakers who have suffered traumatic brain injury: such speakers perform well when asked to utter a short word, but struggle when asked to produce a longer string of sounds. A better understanding of the interaction between speech sounds and sentence structure will lead to improvements in the treatment of speech disorders, and in the quality of human-machine communication.Read moreRead less
An instrumental investigation of consonant sequences in a northern Australian language. Australian indigenous languages are of great interest, due in part to their unique phonetic structure relative to many other languages of the world. Most advances in speech science and phonetic theory are based on studies of English, or other European languages, yet an important goal of phonetic science is to account for speaking and listening processes that are deemed to be universal. Our proposal seeks ....An instrumental investigation of consonant sequences in a northern Australian language. Australian indigenous languages are of great interest, due in part to their unique phonetic structure relative to many other languages of the world. Most advances in speech science and phonetic theory are based on studies of English, or other European languages, yet an important goal of phonetic science is to account for speaking and listening processes that are deemed to be universal. Our proposal seeks to address key aspects of current phonetic theory and models of speech sound production, by providing data from an indigenous Australian language.Read moreRead less
Uptalk in Australian English Intonation. Australian English speakers often use rising instead of falling intonation at the end of sentences which are not questions. This phenomenon of uptalk is one of the unique traits of the Australian English accent. The project will model uptalk by analyzing spoken dialogues from 150 speakers from three major populations, Sydney, Melbourne, and regional Victoria. The intonation patterns of regional and non-Sydney populations have been poorly investigated ....Uptalk in Australian English Intonation. Australian English speakers often use rising instead of falling intonation at the end of sentences which are not questions. This phenomenon of uptalk is one of the unique traits of the Australian English accent. The project will model uptalk by analyzing spoken dialogues from 150 speakers from three major populations, Sydney, Melbourne, and regional Victoria. The intonation patterns of regional and non-Sydney populations have been poorly investigated, so this kind of study is needed to get a more complete understanding of Australian English intonation and the Australian accent. Outcomes will include publications on intonation and laboratory phonology, sociophonetics, and a working model of intonation that can be implemented in speech output systems for Australian English.Read moreRead less
Using visual science to reduce the dangers of night driving. This project aims to develop novel tests of visual function relevant to the modern night driving environment. Night driving is challenging for all drivers and has been linked to poor visibility under low light conditions. This project will characterise the visual challenges of the modern night driving environment, develop visual tests that incorporate the dynamic light levels typical of night-time roads and assess the association of th ....Using visual science to reduce the dangers of night driving. This project aims to develop novel tests of visual function relevant to the modern night driving environment. Night driving is challenging for all drivers and has been linked to poor visibility under low light conditions. This project will characterise the visual challenges of the modern night driving environment, develop visual tests that incorporate the dynamic light levels typical of night-time roads and assess the association of these tests with night driving performance. The outcomes will contribute new knowledge regarding dynamic visual processing and the ageing visual system and will inform vision testing, potential interventions to improve visual function for night driving and reduce the dangers of night driving.Read moreRead less
A computational and experimental investigation into the organisation of letters in reading. In alphabetical languages, people need to learn to organise individual letters into groups so that they can read efficiently. This project will develop a model of this process, which will allow great insight into this key aspect of reading in terms of what the most efficient way of doing this is and what may go wrong and cause reading problems.
Centre-surround interactions in ageing human vision. Australia has a rapidly ageing population. This project will study how ageing affects the visual perception of objects presented on non-uniform backgrounds. Our ability to discriminate objects from their backgrounds is key to most natural visual tasks. The visual processes involved are known as centre-surround interactions, and are considered fundamental building blocks to human perception. This project will significantly advance our knowledge ....Centre-surround interactions in ageing human vision. Australia has a rapidly ageing population.

Our ability to discriminate objects from their backgrounds is key to most natural visual tasks. The visual processes involved are known as centre-surround interactions, and are considered fundamental building blocks to human perception. This project will significantly advance our knowledge of which spatial visual mechanisms are altered due to age, supplying key information for understanding and improving visual environments for the elderly, as well as increasing knowledge of the brain mechanisms susceptible to the ageing process.Read moreRead less

This project will benefit the 1 in 20 Australian children who stutter and their families. We will learn for the first time how stuttering impacts on child development in the early school years and document the relationship between stuttering and other childhood conditions. The study will produce much needed information about recovery from stuttering and stuttering persistence. Therefore new knowledge will result to inform the scientific community and provide professionals and families with much needed evidence-based information about stuttering progression. Together this information will inform intervention approaches and help direct resources to those children who need them most. Read moreRead less
Thalamic inputs and cortical microcircuitry underlying the functional architecture of the visual cortex. This project seeks to reveal the fundamental circuitry of the visual cortex that enables visual perception. Such understanding is essential not only for explaining many perceptual disturbances, but also for providing a neuronal basis for developing functionally useful prostheses for the blind.
Learning to talk whitefella way. Many Indigenous children speak Aboriginal English or 'Kriol', which often sounds very different to Standard Australian English. Understanding the differences between these languages, and how 'Kriol' affects the learning of English, will help us to better assist Indigenous children to learn English and likely improve their educational outcomes.
