The new voice of Multicultural Australian English. This project aims to generate an integrated and inclusive model of Australian-English, through phonetic analysis of the spoken language used by adolescents from a range of ethnic backgrounds. Australia is one of the most ethnically diverse countries in the world yet the complex relationship between speech production and cultural diversity is largely unknown in 21st century multicultural Australia. This project aims to establish how adolescents f ....The new voice of Multicultural Australian English. This project aims to generate an integrated and inclusive model of Australian-English, through phonetic analysis of the spoken language used by adolescents from a range of ethnic backgrounds. Australia is one of the most ethnically diverse countries in the world yet the complex relationship between speech production and cultural diversity is largely unknown in 21st century multicultural Australia. This project aims to establish how adolescents from different ethnicities use speech patterns to symbolically express their diverse sociocultural identities. The project expects to inform sociophonetic theories of variation, ethnicity, and identity, providing a framework for supporting sociocultural cohesion in Australia. Read moreRead less
The effect of sound change on children's speech in community diversity. This project aims to explain how children's speech processing adapts to cultural and linguistic diversity and how such adaptation may seed sound change in language. Using acoustic and articulatory (ultrasound) methods, the project intends to explain how children rapidly and authentically acquire the intricately nuanced accents of their communities. The project aims to advance theories of language variation and change by prov ....The effect of sound change on children's speech in community diversity. This project aims to explain how children's speech processing adapts to cultural and linguistic diversity and how such adaptation may seed sound change in language. Using acoustic and articulatory (ultrasound) methods, the project intends to explain how children rapidly and authentically acquire the intricately nuanced accents of their communities. The project aims to advance theories of language variation and change by providing new insights into the forces that shape the sounds of language. An understanding of how children's speech patterns develop and ultimately converge to local norms has implications for the social integration of second language learning children and refugee/asylum seekers, and for clinical and speech technology applications for children.Read moreRead less
Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic ....Investigation of the component distributions of pause duration in spontaneous speech: Constraints for models of language production. We have discovered that the distribution of pause durations in spontaneous speech of individual speakers can be decomposed into at least two log-normal distributions. Our project will investigate this finding and provide a foundation for new research relevant to language production models. This will be achieved by determining the semantic, lexical, psycholinguistic, physiological, and acoustic concomitants of each component distribution and by investigating the impact of selected variables on the shape and location of each. The project has important implications for models of language production and applied problems involving automatic speech recognition, forensic speaker identification, and human communication disorders.Read moreRead less
Learning from others: Inductive reasoning based on human-generated data. Most of the data we see every day, from politics to gossip, comes from other people. Making inferences about such data is difficult because the people who provided it may have biases or limitations in their knowledge that we do not know about and must figure out. This project uses a series of experiments tied to normative computational models of social reasoning to explore how people solve this problem. This work has the po ....Learning from others: Inductive reasoning based on human-generated data. Most of the data we see every day, from politics to gossip, comes from other people. Making inferences about such data is difficult because the people who provided it may have biases or limitations in their knowledge that we do not know about and must figure out. This project uses a series of experiments tied to normative computational models of social reasoning to explore how people solve this problem. This work has the potential to make a major impact in understanding how information is understood and shared, especially when it is about topics that people lack firsthand knowledge about, like climate change. The computational models also have applications to the development of expert systems upon which our information economy relies.Read moreRead less
Using language to predict cognitive outcomes in old age. This project aims to understand the relationship between linguistic complexity metrics and cognitive decline in old age. The project will test the hypothesis that high linguistic complexity scores reflect the ability to strategically optimise processing in the face of age-related reductions in processing capacity. By studying the relation between complexity scores and real-time information processing (measured via electroencephalography) a ....Using language to predict cognitive outcomes in old age. This project aims to understand the relationship between linguistic complexity metrics and cognitive decline in old age. The project will test the hypothesis that high linguistic complexity scores reflect the ability to strategically optimise processing in the face of age-related reductions in processing capacity. By studying the relation between complexity scores and real-time information processing (measured via electroencephalography) across the adult lifespan (20–80 years), this project will develop a simple and accurate marker of the individual balance between processing capacity and strategy. This project has the potential to increase quality of life for the elderly and reduce costs of age-related cognitive impairment.Read moreRead less
Phonological effects on the development of inflectional morphology. This project investigates the mechanisms underlying typically developing children's variable omission of inflectional morphemes (for example, plural, past tense). The results will have significant implications for the evaluation and design of interventions for language-delayed populations where serious problems of communication persist.
Preserving and reviving language and culture of Norfolk Island. The project will help revive the endangered Norfolk Island language, thereby strengthening the sense of identity of the Norfolk Islanders. It will help achieve greater visibility of the language through an exhibition, interpretive signage and production of educational resources. The training provided will open up employment opportunities in education and cultural tourism in a remote community.
Involvement of the Human Retinal Endothelial Cell in Blinding Eye Disease. Endothelial cells line the blood vessels of the vascular networks that circulate blood through the tissues. The molecular constitution of each endothelial cell is different and specific to function, but may predispose to tissue-specific disease. Retinal endothelial cells ensure the nutrition and protection of a tissue critical to vision, but are key participants in retinal ischemic, inflammatory and infectious diseases th ....Involvement of the Human Retinal Endothelial Cell in Blinding Eye Disease. Endothelial cells line the blood vessels of the vascular networks that circulate blood through the tissues. The molecular constitution of each endothelial cell is different and specific to function, but may predispose to tissue-specific disease. Retinal endothelial cells ensure the nutrition and protection of a tissue critical to vision, but are key participants in retinal ischemic, inflammatory and infectious diseases that threaten vision. This project will investigate molecular activities of retinal endothelial cells that are relevant to retinal disease processes and explore future biological therapies directed against the human retinal endothelial cell that address efficacy and safety deficiencies of current treatments.Read moreRead less
The relationship between speech production and perception in Australian language speakers: implications for speech development and learning in Aboriginal children. Chronic ear infection blights the life of at least 50% of Aboriginal Australians. In a vicious cycle that extends from generation to generation, it leads to hearing loss, educational disadvantage, socio-economic disadvantage and environmental depredation, which once again leads to ear (and many other) infections. This is a unique atte ....The relationship between speech production and perception in Australian language speakers: implications for speech development and learning in Aboriginal children. Chronic ear infection blights the life of at least 50% of Aboriginal Australians. In a vicious cycle that extends from generation to generation, it leads to hearing loss, educational disadvantage, socio-economic disadvantage and environmental depredation, which once again leads to ear (and many other) infections. This is a unique attempt by researchers across academic disciplines to study the role of language in educational disadvantage and whether this disadvantage might be made worse for Aboriginal children by the early use of English at school. We ask whether, on purely acoustic or linguistic grounds, communicating in an Aboriginal language might offer improved educational and health outcomes for Aboriginal children in the early years.Read moreRead less
