Voice analysis offers a promising, non-invasive method for detecting heart failure congestion. This cost-effective approach could revolutionize patient monitoring and risk prediction, complementing current diagnostic tools.
Area of Science:
- Biomedical Engineering
- Cardiology
- Speech Science
Background:
- Chronic heart failure (CHF) management faces challenges in early congestion detection.
- Current methods are often invasive or require specialized hardware.
- Voice analysis presents a non-invasive, cost-effective alternative for CHF monitoring.
Purpose of the Study:
- To review the current state-of-the-art in voice analysis for heart failure.
- To explore the potential of vocal biomarkers in diagnosing and monitoring CHF.
- To identify challenges and future directions in this research area.
Main Methods:
- Literature review of voice feature extraction techniques.
- Analysis of studies applying voice analysis to heart failure patients.
- Discussion of technological capabilities and limitations.
Main Results:
- Voice analysis can detect subtle physiological changes related to heart failure.
- Potential for identifying vocal biomarkers indicative of congestion and risk.
- Demonstrates feasibility as a telemonitoring tool.
Conclusions:
- Voice analysis is a promising, non-invasive technology for heart failure management.
- Further research and interdisciplinary collaboration are needed to realize its full potential.
- Vocal biomarkers could enhance early detection, risk prediction, and remote monitoring of CHF.

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
