Machine Unlearning reveals that the Gender-based Violence Victim Condition can be detected from Speech in a Speaker-Agnostic Setting

원문 초록

This study addresses the critical issue of gender-based violence's (GBV) impact on women's mental health. GBV, encompassing physical and sexual aggression, often results in long-lasting adverse effects for the victims, including anxiety, depression, post-traumatic stress disorder (PTSD), and substance abuse. Artificial Intelligence (AI)-based speech technologies have proven valuable for mental health assessments. However, these technologies experience performance challenges when confronted with speakers whose data has not been used for training. Our research presents a novel approach to speaker-agnostic detection of the gender-based violence victim condition (GBVVC), focusing on the development of robust AI models capable of generalization across diverse speakers. Leveraging advanced deep learning models and domain-adversarial training techniques, we minimize speaker identity's influence, achieving a 26.95% relative reduction in speaker identification ability while enhancing the GBVVC detection by a 6.37% relative improvement in the accuracy. This shows that models can focus on discriminative paralinguistic biomarkers that enhance the GBVVC prediction, and reduce the subject-specific traits' impact. Additionally, our model's predictions moderately correlate with pre-clinical PTSD symptoms, emphasizing the link between GBV and mental health. This work paves the way for AI-powered tools to aid mental health professionals in addressing this societal issue, offering a promising baseline for further research.
