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
Understanding the relationship between child maltreatment and language competence: An evidential interviewing perspective. This research aims to develop the first comprehensive and controlled examination of the oral language profiles of maltreated children and how these impact performance in an investigative interview paradigm. This examination is essential for developing strategies for improving the elicitation of evidence from child abuse witnesses. By improving child witness evidence, this re ....Understanding the relationship between child maltreatment and language competence: An evidential interviewing perspective. This research aims to develop the first comprehensive and controlled examination of the oral language profiles of maltreated children and how these impact performance in an investigative interview paradigm. This examination is essential for developing strategies for improving the elicitation of evidence from child abuse witnesses. By improving child witness evidence, this research will improve the prosecution and conviction rates of child abuse offences, which will have a deterrent effect on potential offenders. Finally, this research will reduce the stress of witnesses involved in the legal process and provide better screening of children in need of specialised language intervention.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
The measurement and prediction of police interviewing performance and the dissemination of good practice through a distributive workplace learning system. This research aims to develop the first ever standardised measures of police interviewers' performance, focusing on interviews about sexual offences. Standardised measures are essential for quality control evaluation, identifying training needs, assigning workload, predicting case outcome and benchmarking organisation capabilities. By improvin ....The measurement and prediction of police interviewing performance and the dissemination of good practice through a distributive workplace learning system. This research aims to develop the first ever standardised measures of police interviewers' performance, focusing on interviews about sexual offences. Standardised measures are essential for quality control evaluation, identifying training needs, assigning workload, predicting case outcome and benchmarking organisation capabilities. By improving the quality of police interviews about sexual offences, this research will improve the reporting, prosecution and conviction rates of sexual offences, which will have a deterrent effect on potential offenders. Further, this research will reduce the stress of witnesses and suspects involved in the legal process and reduce burnout of police interviewers by increasing competency and job satisfaction.Read moreRead less
Improving the competency of police officers in conducting investigative interviews of children. The current research program aims to identify factors that promote and sustain competent police interviewing of children. Although 'best-practice' guidelines in investigative interviewing have been developed, these guidelines are under-utilised by police officers in practice. Research is therefore needed to identify barriers to the implementation of these 'best-practice' guidelines and to test interve ....Improving the competency of police officers in conducting investigative interviews of children. The current research program aims to identify factors that promote and sustain competent police interviewing of children. Although 'best-practice' guidelines in investigative interviewing have been developed, these guidelines are under-utilised by police officers in practice. Research is therefore needed to identify barriers to the implementation of these 'best-practice' guidelines and to test interventions designed to improve their uptake. The expected outcome of this project is the development of interventions that will improve the quality of police training in investigative interviewing. This will increase the quality of evidence obtained from children, especially those who are victims of child abuse.Read moreRead less
