This project aims to uncover the connected perception and production processes that underpin these language challenges for children with hearing loss, focussing on a speech patterns also found in younger normal-hearing toddlers, and using innovative technologies that can generalize to the clinical practice. The project outcomes will significantly advance theories of child language development, and promise to inform more accurate and better-targeted intervention for children with hearing loss, providing social benefit by improving their listening and speaking skills.Read moreRead less
How Strict is the Mother Tongue? Using Dialects to Probe Early Speech Perception and Word Recognition. This project will 1)advance knowledge of toddler word representations and their developmental precursors; 2) contribute to theories of phonological vs phonetic properties of spoken language; 3) explain how experience with the ambient language shapes children's phonological and lexical development. Moreover, the findings will 4) offer crucial new insights into sources of developmental disorders ....How Strict is the Mother Tongue? Using Dialects to Probe Early Speech Perception and Word Recognition. This project will 1)advance knowledge of toddler word representations and their developmental precursors; 2) contribute to theories of phonological vs phonetic properties of spoken language; 3) explain how experience with the ambient language shapes children's phonological and lexical development. Moreover, the findings will 4) offer crucial new insights into sources of developmental disorders (language delay, dyslexia) leading to improved early diagnosis and treatment; 5) bear on issues of second language learning; and by understanding the process by which young learners handle dialect variability, 6) provide insights into how automatic speech recognition systems can be made more robust to dialectal and foreign accent differences.

Development of second language phonetic and phonological categories. The majority of the world's population speaks two or more languages, yet we know little about how multiple languages are accommodated within a single speaker. Why do children appear to learn a second language 'like a native' but adults invariably develop a clearly perceptible foreign accent? This project investigates a little-known fact - adult second language speakers also 'hear' with a foreign accent. As Australia becomes inc ....Development of second language phonetic and phonological categories. The majority of the world's population speaks two or more languages, yet we know little about how multiple languages are accommodated within a single speaker. Why do children appear to learn a second language 'like a native' but adults invariably develop a clearly perceptible foreign accent? This project investigates a little-known fact - adult second language speakers also 'hear' with a foreign accent. As Australia becomes increasingly multilingual increasing our understanding of the human capacity for language learning would strengthen Australia's social and economic fabric by leading to improved educational practices, work prospects for migrants and, most importantly, understanding between cultures.Read moreRead less
Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directiona ....Relationship of retinal directionality to human retinal anatomy variations. This project aims to improve measurement of retinal directionality, which is the reduction in brightness when a light beam’s entry into the human eye is shifted from the centre to the edge of the pupil. This influences retinal image quality and can be used to measure changes in shape of the peripheral eye. This project will apply advanced technologies in holography, and heads-up displays to explore how retinal directionality changes during accommodation (focusing). The expected outcome is improved understanding of retinal stretching changes during focusing. The benefit is that the project will lead to advancements in retinal imaging.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
Removing the blinkers: a wider study of the human eye. Peripheral aberrations, wide-field retinal imaging and optical parameters. This project will study peripheral (side vision) optics of the human eye and its role in the limits of visual performance. This will improve ocular measurements and contribute towards improved diagnosis and treatment of ocular diseases and short-sightedness.
Advanced methods for intraocular imaging. The ability to image the retina of the human eye at high resolution is fundamental to improving understanding of ocular physiology, ocular optics and disease diagnosis. This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will ....Advanced methods for intraocular imaging.

This project applies the relatively new application of active optics to vision science. This project will investigate the advantages of using new beam shaping techniques for characterising the optics of the eye, improving retinal imagery and improving fixation stability. This project will achieve three-dimensional holography of human eyes and develop holography plates for correcting the aberrations of eyes. Expected outcomes are not-before experienced resolution images of the retina and better understanding of the optical characteristics of the refractive surfaces and media in the eye.Read moreRead less
Unveiling the mystery of tone perception: How does native language prosody affect adults' perception of foreign tones? This project provides new knowledge about how humans perceive non-native lexical tone categories. The results of this large-scale cross-language study will indicate how native languages constrain human perception of non-native speech (consonants, vowels, intonation). These data will greatly facilitate the research in second language acquisition and teaching, speech perception mo ....Unveiling the mystery of tone perception: How does native language prosody affect adults' perception of foreign tones? This project provides new knowledge about how humans perceive non-native lexical tone categories. The results of this large-scale cross-language study will indicate how native languages constrain human perception of non-native speech (consonants, vowels, intonation). These data will greatly facilitate the research in second language acquisition and teaching, speech perception modeling including automatic speech recognition with tone languages, human speech processing. The findings will also be useful to clinical speech and hearing research for speech and hearing impaired persons, and commercial applications in foreign language teaching, and computer assisted language learning for language learners.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.
Does word similarity across languages help or hinder bilingual speakers? This project aims to understand in more detail how bilinguals can accurately speak in both their languages. Speaking is a complex skill, particularly if you have two languages to choose from, which will be true for over half of Australia’s population by 2025. This project aims to investigate the factors that influence speech production in both monolinguals and bilinguals including those with language impairment, and develop ....Does word similarity across languages help or hinder bilingual speakers? This project aims to understand in more detail how bilinguals can accurately speak in both their languages. Speaking is a complex skill, particularly if you have two languages to choose from, which will be true for over half of Australia’s population by 2025. This project aims to investigate the factors that influence speech production in both monolinguals and bilinguals including those with language impairment, and develop a better bilingual theory. The benefit of this new theory will be to provide a clear basis for diagnosis and treatment for children in bilingual households who have problems learning to speak, and for bilingual people with language problems after a stroke or dementia.Read moreRead less
