Query: Detecting Dementia from Speech and Transcripts using Transformers   Alzheimer's disease (AD) constitutes a neurodegenerative disease with serious
consequences to peoples' everyday lives, if it is not diagnosed early since
there is no available cure. Because of the cost of examinations for diagnosing
dementia, i.e., Magnetic Resonance Imaging (MRI), electroencephalogram (EEG)
signals etc., current work has been focused on diagnosing dementia from
spontaneous speech. However, little work has been done regarding the conversion
of speech data to Log-Mel spectrograms and Mel-frequency cepstral coefficients
(MFCCs) and the usage of pretrained models. Concurrently, little work has been
done in terms of both the usage of transformer networks and the way the two
modalities, i.e., speech and transcripts, are combined in a single neural
network. To address these limitations, first we employ several pretrained
models, with Vision Transformer (ViT) achieving the highest evaluation results.
Secondly, we propose multimodal models. More specifically, our introduced
models include Gated Multimodal Unit in order to control the influence of each
modality towards the final classification and crossmodal attention so as to
capture in an effective way the relationships between the two modalities.
Extensive experiments conducted on the ADReSS Challenge dataset demonstrate the
effectiveness of the proposed models and their superiority over
state-of-the-art approaches.
