Voice-based Outcome Identification and Clinical Evaluation in Heart Failure

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.

Pre-Symptomatic Detection of Impending Decompensation in Heart Failure Through Voice Data

PRE-DETECT-HF is a prospective, single-arm observational study evaluating a voice-based machine learning algorithm for early detection of heart failure decompensation. 123 patients hospitalized for acute decompensated or de-novo heart failure will be enrolled across three sites in the Netherlands and Spain. Patients make daily voice recordings via a smartphone app and answer symptom questions for 6 months. The algorithm analyzes voice patterns compared to a baseline recording at discharge. Treatment decisions are based on symptom data only; voice-based predictions are analyzed retrospectively after study completion. The primary endpoint is sensitivity of the voice-based software in detecting heart failure deterioration, defined as heart failure hospitalization, or intensification of heart failure therapy. Secondary endpoints include app adherence, usability, and associations between voice data and blood biomarkers.
