Vocal Biomarkers Market Report 2025

This Vocal Biomarkers market report provides a comprehensive analysis of the market’s characteristics, size, and growth, including segmentation, regional and country-level breakdowns, competitive landscape, market shares, trends, and strategies. It also tracks historical and forecasted market growth across various geographies.

The vocal biomarkers market size has grown rapidly in recent years. It will grow from $2.84 billion in 2024 to $3.37 billion in 2025 at a compound annual growth rate (CAGR) of 18.8%. The growth in the historic period can be attributed to the need for early detection of diseases, vocal biomarker applications in lie detection, demand for vocal biomarkers in the defense sector, increasing incidence of mental disorders, and rising chronic diseases such as cardiovascular disease.

The vocal biomarkers market size is expected to see rapid growth in the next few years. It will grow to $6.66 billion in 2029 at a compound annual growth rate (CAGR) of 18.6%. The growth in the forecast period can be attributed to rising cases of neurological and psychological disorders, high demand for novel diagnostic procedures, a growing incidence of dementia, increasing awareness about the efficacy of vocal biomarkers, and increasing diagnostic procedures. Major trends in the forecast period include advancements in biomarker technology, rapid adoption of advanced technologies, high investments in R&D, improvements in diagnostic capabilities, and advanced technology in the medical industry.

The increasing prevalence of neurological and psychological disorders is expected to drive the growth of the voice biomarkers market in the coming years. Neurological disorders affect the nervous system, while psychological disorders impact mood, thinking, and behavior. The rise in these conditions can be attributed to factors such as higher stress levels, aging populations, lifestyle changes, and improved awareness and diagnostic capabilities. Voice biomarkers are used to detect and monitor disease-specific changes in speech patterns, pitch, and rhythm non-invasively, offering valuable insights into the presence and progression of these disorders. For example, in April 2024, the data published by alzheimers.gov, a US-based Department of Health and Human Services (HHS), revealed that over 6 million Americans aged 65 and older are living with Alzheimer’s disease in 2024, with projections showing this number will exceed 13 million by 2060. Additionally, according to the National Institute of Mental Health, a US-based entity, 30 million of the 59.3 million adults with AMI (50.6%) received mental health treatment in the past year. Therefore, the growing number of neurological and psychological disorders is contributing to the expansion of the voice biomarkers market.

Leading companies in the vocal biomarkers market are concentrating on developing cutting-edge technologies, such as Monitor Vocal Biomarkers, to improve disease detection accuracy, enhance patient monitoring, and facilitate early intervention for various health conditions. Monitor Vocal Biomarkers involves analyzing voice samples to identify indicators of both physiological and psychological health. For example, in November 2024, Sonde Health, a US-based digital health company, introduced Sonde Cognitive Fitness, a voice-based cognitive fitness tracker designed to assess cognitive effort in real time. This tracker collects voice samples from common smart devices and analyzes vocal biomarkers to evaluate cognitive effort.

In January 2023, Cambridge Cognition Ltd., a UK-based neuroscience technology company, completed the acquisition of Winterlight Labs for approximately $0.008.6 million. This strategic move consolidates Cambridge Cognition's leadership in the vocal biomarker market, positioning the company to capitalize on substantial growth opportunities. The acquisition enables Cambridge Cognition to offer a comprehensive range of voice-based solutions for clinical research and healthcare applications. Winterlight Labs, based in Canada, specializes in developing vocal biomarkers used to assess cognitive and mental health conditions.

Vocal biomarkers are quantifiable characteristics of speech that offer insights into an individual's health and overall condition. These markers are derived from analyzing vocal elements such as pitch, tone, rhythm, volume, and speech patterns. They serve purposes such as detecting, monitoring, and predicting various health issues such as mental health disorders, neurological conditions, and respiratory ailments.

The primary categories of vocal biomarkers include frequency, amplitude, error rate, vocal rise or fall time, phonation time, voice tremor, pitch, and others. Frequency in vocal biomarkers indicates the rate of vibration in sound waves, providing valuable information about a person's health and emotional state. These biomarkers find application across a wide range of conditions including psychiatric disorders, neurological disorders, respiratory issues, cardiovascular conditions, traumatic brain injury (TBI), and others. They serve diverse populations including children, infants, and adults, and are utilized by hospitals, clinics, academic institutions, research centers, and other entities.
