ADReasoner: Acoustic-Linguistic Cue-Aware Reinforcement Learning for Explainable Alzheimer's Disease Detection from Speech

Speech-based Alzheimer's Disease (AD) detection holds significant promise due to its scalable and non-invasive nature. However, current Speech Large Language Models (SpeechLLMs), similar to conventional AD detection systems, still treat AD detection primarily as a simple categorical classification task. This paradigm p...

Disentangling Acoustic Cues in Alzheimer's Pathology and Perception: The Roles of Language and Gender

Acoustic biomarkers show promise for detecting Alzheimer's Disease (AD), yet whether the cues driving diagnostic AI align with those salient to human listeners is underexplored across languages and genders, where pathological markers and perceptual strategies differ. We train models to predict clinical AD status (patho...
