CONSEN: Complementary and Simultaneous Ensemble for Alzheimer’s Disease Detection and MMSE Score Prediction

Abstract

This paper proposes a novel method for Alzheimer’s disease detection and MMSE prediction using a complementary and simultaneous ensemble (CONSEN) algorithm based on multilingual spontaneous speech. We define pause and intervention of speech to form disfluency features, as well as several acoustic features to train generalized models. With the help of the proposed CONSEN algorithm, our model achieves the best performance of 86.69% for AD detection and 3.727 RMSE for MMSE prediction, which is placed first rank in both tasks in ICASSP Signal Processing Grand Challenge: ADReSS-M Challenge 2023.
