Tackling the ADRESSO Challenge 2021: The MUET-RMIT System for Alzheimer’s Dementia Recognition from Spontaneous Speech

This paper addresses the Interspeech Alzheimer’s Dementia Recognition through Spontaneous Speech only (ADReSSo) challenge 2021. The objective of our study is to propose the approach to a three task automated screening that will aid in distinguishing between healthy individuals and subjects with dementia. The first task is to differentiate between speech recordings from individuals with dementia. The second task requires participants to estimate the Mini-Mental State Examination (MMSE) score based on an individual’s speech. The third task requires participants to leverage speech recordings to identify whether individuals have suffered from cognitive decline. Here, we propose a system based on functionals of deep textual embeddings with special preprocessing steps integrating the effect of silence segments. We report that the developed system outperforms the challenge baseline for all three tasks. For Task 1, we achieve an accuracy of 84.51% compared to the baseline of 77.46%, for Task 2, we achieve a root-mean-square-error (RMSE) of 4.35 compared to the baseline of 5.28, and for Task 3, we achieve an average-f1score of 73.80% compared to the baseline of 66.67%. These results are a testament of the effectiveness of our proposed system.
