LoRA-Tuned Large Language Models for Dementia Detection via Multi-View Speech-Derived Features

Jonghyeon Park, Olivier Jiyoun Jung, Myungwoo Oh

Early detection of dementia enables timely intervention, and reflecting cognitive impairment, spontaneous speech offers a non-invasive screening modality. Conventional approaches often focus on a single representational dimension -- such as acoustic descriptors, pause modeling, a…

Listening Between the Lines: Joint Learning of ASR Embeddings and LLM-Augmented Linguistics for Dementia Detection

Olivier Jiyoun Jung, Jonghyeon Park, Myungwoo Oh

Early detection of dementia through speech analysis offers a non-invasive screening alternative, but capturing both acoustic and linguistic biomarkers remains challenging. We propose a multimodal framework leveraging Whisper for dual-purpose extraction: acoustic representations f…
