Harmony is an entrepreneuship project I contributed to at UC Berkeley, where my developed machine learning models to predict dementia through voice biomarkers. As the sole designer in this interdisciplinary neurotechnology team, I was responsible for transforming AI technology into an empathetic voice user interface (VUI). This work focused on creating a context-aware, emotionally resonant interface that enabled more natural, compassionate interactions with the system, bridging the gap between advanced AI and human-centered design.
early dementia detection just through voice
Our team has developed two machine learning-based regression models to screen for mild cognitive impairment, trained on eight voice biomarkers. These models have shown over 80% accuracy in initial testing, and we are continuing to collect data to refine and improve their precision.
