Vocal Biomarkers: The Future of Non-Invasive Health Monitoring

In recent years, advancements in digital health technologies have opened new avenues for diagnosing and monitoring medical conditions without the need for invasive procedures. One of the most promising areas is the study of vocal biomarkers—measurable characteristics in human voice that can indicate physiological and psychological states. These subtle changes in speech patterns, tone, or pitch can serve as early indicators of various health conditions, offering a non-intrusive and accessible method for healthcare monitoring.

A vocal biomarker is essentially a distinct feature in speech that correlates with a specific health condition. These features may include variations in voice pitch, frequency, tremor, speech rate, and even pauses between words.
