Voice Biomarkers

The voice-cloning experiment also showed that linguistic cues contributed substantially to model performance. Controlled-content voice cloning supported that acoustic biomarkers alone carried discriminative information. Performance above chance on standardized passages supported transferable non-linguistic vocal signals. The study hypothesizes that raw audio contains voice biomarkers relevant to depression and anxiety. The study addresses the need for objective and scalable screening methods that identify depressive and anxiety symptoms from speech.
