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
Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classe ....Using written language to probe speech recognition models. Speech recognition models fall into two principal classes, with fundamentally different processing architectures. Feedback models (e.g. TRACE, McClelland & Elman, 1986) allow lexical knowledge to exert top-down control over phonemic analysis. Feedforward models (e.g. Merge, Norris, McQueen & Cutler, 2000) assume that information flow is entirely bottom-up. Our project adopts an innovative approach to testing between these model classes, by examining the influence of written-word knowledge on speech perception. To distinguish the models, contrasts must test different processing levels and examine strategy effects. TRACE favors broad effects with limited strategic influence; Merge favors lexical effects that are necessarily sensitive to strategic factorsRead 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
Language typology and cognitive effects of language learning. This project aims to map, in older adults and preschool-age children, the extent and nature of cognitive benefit from training in a foreign language. Learning a language is recognised to be beneficial in various ways, but this project investigates whether it matters which language one learns. The project will compare the resulting cognitive changes to language learners across different languages to test whether the benefit is uniquely ....Language typology and cognitive effects of language learning. This project aims to map, in older adults and preschool-age children, the extent and nature of cognitive benefit from training in a foreign language. Learning a language is recognised to be beneficial in various ways, but this project investigates whether it matters which language one learns. The project will compare the resulting cognitive changes to language learners across different languages to test whether the benefit is uniquely effective. It will also gauge whether these changes occur when learning is easier in childhood compared to when it is harder later in life. The project findings will inform the development of linguistic, social, and educational programs to optimise cognitive function both for childhood development and healthy ageing, especially in Australia where second language acquisition is lower compared to other countries.Read moreRead less
The perception/production link in child language. Children with hearing loss experience continuing language difficulties, with major knock-on effects on educational and social outcomes. 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.

Origins of Phonology and Lexicon: Abstract representations before 6 months. Language is one of the most sophisticated human abilities, yet infants learn it easily. The current view is that the origins of language are abstract representations of consonants and vowels that start to form at 6-10 months. However, recent evidence shows that abstraction begins before 3 months, and that carer-infant conversations are vital to the process. This study involves tracking infants’ behavioural and brain deve ....Origins of Phonology and Lexicon: Abstract representations before 6 months. Language is one of the most sophisticated human abilities, yet infants learn it easily. The current view is that the origins of language are abstract representations of consonants and vowels that start to form at 6-10 months. However, recent evidence shows that abstraction begins before 3 months, and that carer-infant conversations are vital to the process. This study involves tracking infants’ behavioural and brain development from 1 to 18 months and analysing carer-infant speech, to determine how early abstraction supports vocabulary growth, how carer speech assists this process, and what early conditions predict language development, thus benefiting earlier identification of language delay, and saving significantly on later remediation.Read moreRead less
