About the research project
Neurodegenerative conditions like dementia affect millions and have no known cure, making early detection important. In Australia, more than 459,000 people are living with dementia, at a cost of $15 billion per year. With ageing populations, the prevalence is rapidly rising and is expected to be over 1 million by 2058 (Health Direct Australia, 2019). The primary aim of this project is to investigate AI based early detection algorithms using the speech and text data collected from people with neurodegenerative conditions.
There is evidence that spoken language is an informed representation of an individual's cognitive status (Asgari et al., 2017) and that speech analysis could potentially be used as a quick test of 'pre-symptomatic' cognitive status (Kindell et al., 2017). Recently, new research evidence shows that spoken language reveals cognitive status, and speech analysis can classify Alzheimer's disease (AD), mild cognitive impairment (MCI), and healthy control (HC) group (Luz et al., 2020). However, the current analysis of language impairment depends on intensive labor, since high-fidelity speech transcripts are needed (Asgari et al., 2017). Hence this multi-discipline project aims to fill the gap with an automated language-based assessment that offers a broad availability for potential patients with neurodegenerative disorders and facilitates further corresponding treatment.
We will train an algorithm to differentiate those adults with normal cognition from those with accelerated cognitive decline. Machine learning and knowledge discovery methods will map how combinations of speech features discriminate normal ageing from accelerated cognitive ageing. Mixed methods of audio and text analysis are emerging as potential early indicators of cognitive decline. Therefore, there are two processes will be conducted: audio analysis, and transcript analysis.
