Overcoming language barriers in healthcare: towards safe and effective communication when patients or clinicians use a second language. An international team of scholars will study language barriers in Australia's healthcare syste; arising from growing numbers of patients and clinicians not speaking English as their first language. The project's results will lay the foundation for future research and point to practical solutions.
Concepts and control in speech production. While humans produce speech fluently in the course of everyday conversation, comparatively little is understood about the underlying mental processes and brain mechanisms. The overall aim of this project is to investigate how the human brain conceives and controls speech output by using state-of-the-art neuroimaging and brain stimulation techniques. The research aims to contribute novel insights into a key human ability with particular relevance for spe ....Concepts and control in speech production. While humans produce speech fluently in the course of everyday conversation, comparatively little is understood about the underlying mental processes and brain mechanisms. The overall aim of this project is to investigate how the human brain conceives and controls speech output by using state-of-the-art neuroimaging and brain stimulation techniques. The research aims to contribute novel insights into a key human ability with particular relevance for speech disorders such as aphasia, while the methods developed for brain stimulation during imaging of speech production aim to expand Australia's capability and technical innovation in the cognitive neuroscience of language.Read moreRead less
How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and ....How the brain produces speech: Neuronal oscillations to neuromodulation. Speech is crucial for facilitating human communication through language, yet there is a lack of clarity about where, when and what type of activity occurs in the brain during key stages of production. This project will use intracranial recordings to characterise neuronal oscillations in combination with direct electrical stimulation, functional neuroimaging and non-invasive brain stimulation to establish critical areas and their timecourses with millisecond resolution. The outcome will be a better theoretical account of the brain mechanisms involved in spoken production. The benefit of this new theoretical account will be a better basis for prevention of post-surgical language impairment and neuromodulatory treatments after brain injury.Read moreRead less
Enhancing Language Learning in Ageing With Exercise. This project aims to determine if exercise improves language learning and consolidation in ageing. There is now compelling evidence for the benefits of exercise on cognition in older adults, however, it is unclear whether exercise improves age-related language problems. The project plans to examine exercise-induced changes in brain activity and biomarkers in an innovative set of studies that seeks to identify the brain mechanisms involved. The ....Enhancing Language Learning in Ageing With Exercise. This project aims to determine if exercise improves language learning and consolidation in ageing. There is now compelling evidence for the benefits of exercise on cognition in older adults, however, it is unclear whether exercise improves age-related language problems. The project plans to examine exercise-induced changes in brain activity and biomarkers in an innovative set of studies that seeks to identify the brain mechanisms involved. The findings are expected to contribute to theories of word learning and cognitive ageing and should advance our understanding of how exercise may be harnessed to optimise language and cognition. This would have practical applications in a range of populations with language and learning difficulties.Read moreRead less
Control of language production and its neural substrates. The ability of humans to say the right word at the right time is a critical, complex and poorly understood function. This research will determine the brain circuits responsible for language production and how this process is affected in Parkinson's disease.
A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in ....A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in sound-to-meaning correspondences as probabilistic cues to attain spoken language. The outcome will be a better neural account of language comprehension and production. The benefit of this new account will be a stronger basis for assessment and treatment of developmental and acquired language impairments.Read moreRead less
Harnessing non-invasive brain stimulation to improve language function in healthy and pathological ageing. This project will examine how the ability of the ageing brain to process language can be improved by non-invasive brain stimulation. The findings have the potential to reveal new ways to treat language impairments in ageing-associated brain injury and disease.

Summary
The Big Australian Speech Corpus: An audio-visual speech corpus of Australian English. Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English. Here we will establish the Big Australian Speech Corpus, which will support a speech science research and developmen ....The Big Australian Speech Corpus: An audio-visual speech corpus of Australian English. Contemporary speech science and technology are driven by the availability of large speech corpora. While audio databases exist for languages spoken in America, Europe and Japan, there is currently no large auditory-visual database of spoken language, and certainly not one for Australian English. Here we will establish the Big Australian Speech Corpus, which will support a speech science research and development using Australian English and facilitate the development of Australian speech technology applications from automatic speech recognition and text-to-speech synthesis used in taxi and other ordering services, to hearing prostheses and talking head aids for learning-impaired children, and a range of security and forensic applications.Read moreRead less
Optimising how the brain processes language in healthy and neurological populations. This research will examine how the ability of the brain to process language can be modified by behavioural experiences, certain drugs and direct brain stimulation. The findings have the potential to reveal new ways to treat language disorders after brain injury or disease.
How does electrical stimulation affect brain networks? This project aims to generate fundamental knowledge about links between neural mechanisms, electrical brain stimulation and brain function. The project aims to improve knowledge about transcranial direct current stimulation (tDCS) and its effects on complex human brain networks.
