AI models for Alzheimer's detection show demographic bias in speech analysis

Researchers have developed AI models to detect Alzheimer's Disease (AD) using acoustic biomarkers, but found significant differences in how these models interpret speech compared to human listeners, particularly across different languages and genders. While models showed alignment with human perception for Mandarin speakers and females, this alignment disappeared for Greek speakers and males, indicating a failure mode in the AI's diagnostic capabilities. The study emphasizes the critical need for population-specific explainability auditing to ensure equitable deployment of clinical speech AI, as global explanations can mask crucial demographic divergences.
