About the study

VOICE-HF is a clinical study designed to evaluate the performance of a novel non-invasive software device (Noah Labs Vox) that uses vocal characteristics to estimate DHF risk and has strong potential for clinical success. This study will compare the performance of Noah Labs Vox with the contemporary performance of commonly used weight-based remote monitoring rules and applications to determine efficacy and safety.
