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

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
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
Predicting Language Skills From Early Auditory Speech Discrimination In Infants With Hearing Loss: Implications For Early Management And Intervention

Summary
Now that newborn hearing checks are available, hearing loss can be picked up soon after birth and hearing aids are fitted shortly after. Although procedures exist for checking that the devices make sounds audible, there is no way to evaluate their effectiveness for supporting a child’s auditory discrimination. This study aims to 1) develop new clinical tools for assessing infants’ auditory discrimination, and 2) determine whether early discrimination predicts spoken language at 3 years of age.
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
Is reading automatic?: Investigating hypnotic elimination of the Stroop effect. Reading in literate people is often characterised as automatic; it cannot be prevented. Recent findings indicate however that hypnotic suggestion may prevent reading. This project: (1) investigates hypnotic elimination/modulation of automatic reading, (2) determines whether these effects arise either because reading does not occur under hypnotic suggestion or because suggestion leads to rapid inhibition of the resul ....Is reading automatic?: Investigating hypnotic elimination of the Stroop effect. Reading in literate people is often characterised as automatic; it cannot be prevented. Recent findings indicate however that hypnotic suggestion may prevent reading. This project: (1) investigates hypnotic elimination/modulation of automatic reading, (2) determines whether these effects arise either because reading does not occur under hypnotic suggestion or because suggestion leads to rapid inhibition of the results of the reading process, and (3) determines which components of the cognitive system can and cannot be affected by hypnotic suggestion. This project provides fresh perspective on how literate people respond to printed stimuli and on the concept of automaticity in cognitive psychology.Read moreRead less
Illuminating the Language-specific and Physiological Motor-control Influences on Children's Production of Lexical Stress. Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody.

Great progress has been made in understanding the production of individual speech sounds but much less is known about the production of prosody. Lexical stress is a type of prosody that reflects the contrast between strong and weak syllables within single words. The ability to achieve this contrastivity shows a protracted developmental trajectory in healthy children and is atypical in some children with autism. How these developmental influences relate to language-specific versus physiological motor-control factors is unknown. This project will address this critical research problem via innovative acoustic investigations. Outcomes will trigger the next generation of speech production models with potential for impact in areas like speech pathology.Read moreRead less
