Global Challenge: Reducing healthcare inequalities through the use of vocal biomarkers

Abstract:

Inequitable access to healthcare remains a critical global issue, particularly in underserved and rural communities impacted by social determinants of health (SDOH). These disparities limit access to quality care and result in poorer health outcomes. This paper explores the potential of data-driven technologies, artificial intelligence (AI), and machine learning to bridge these gaps, with a focus on vocal biomarker techniques as a non-invasive, scalable solution for remote patient monitoring. Vocal biomarkers use voice analysis to detect health conditions, improving diagnostic accuracy and patient adoption rates in both clinical and non-clinical settings.

The research integrates data analysis, physician perspectives, and real-world testing, emphasizing the transformative potential of vocal biomarkers in addressing healthcare inequities while acknowledging challenges such as data governance and equitable technology adoption. The paper evaluates current data-driven healthcare interventions from multiple perspectives, including patients, providers, payers, and startups, emphasizing the need for integrated, holistic solutions.

Key findings from an on-campus study at Vital Audio Inc. are presented, demonstrating the accuracy and usability of vocal biomarker software. Additionally, insights from interviews with healthcare professionals provide a global perspective on the clinical acceptance of this technology and the barriers to its implementation, including cultural attitudes, regulatory requirements, and technological infrastructure. This paper aligns with the UN Sustainable Development Goals of Good Health and Well-Being and Reduced Inequalities, proposing scalable solutions for more equitable healthcare systems. Through this interdisciplinary approach, it offers actionable insights into the role of AI and vocal biomarkers in reducing healthcare disparities. Although the idea of vocal biomarkers has been studied, more extensive data sets need to be created to test models under different demographic and health statuses.

Over the past three years, I struggled to find a clear direction and align with a single goal. However, during the summer before my senior year, I discovered my passion for health equity and exploring actionable solutions for communities affected by social determinants of health. This passion was further ignited through my GLASS x Future Labs internship at Vital Audio Inc., where I merged my technical skills from NYU with my newfound purpose. This experience propelled my journey toward focusing on the Sustainable Development Goals (SDGs) of Good Health and Well-Being and Reduced Inequalities, shaping my future aspirations.

Bio:

Elizabeth Castroverde studied Computer Science with minors in Biomolecular Science and Game Engineering. She is passionate about leveraging technology for social impact, particularly in healthcare, through a multidisciplinary approach.

She has interned at the Mubadala Arabian Center for Climate and Environmental Sciences (ACCESS) as an IoT intern, where she prototyped an environmental sensor network for city-scale meteorological and climate studies. At Vital Audio Inc., she worked as a Biostatistician, applying data analytics to develop innovative remote healthcare solutions using vocal biomarkers. Over the summer, she interned at Alvarez & Marsal as a Corporate Performance Improvement intern, contributing to client-facing projects across the public sector, digital and technology, and financial services.

At school, Elizabeth served as a Resident Assistant, fostering a supportive student community. She was also the President of the World Cultures Club at NYU, promoting cross-cultural exchange, and a member of the Creating Connections Vertically Integrated Project Team, which explored the use of art therapy for patients with Parkinson’s disease.

In her free time, she enjoys arts and crafts, going on walks, and trying new foods. As she continues refining her passions, she hopes to explore diverse cultures and contribute to innovative, technology-driven solutions on a global scale."
