Market Overview

Digital biomarkers are playing a significant role in managing chronic conditions, allowing healthcare professionals to diagnose diseases in real-time to facilitate treatment of patients with chronic conditions. To date, several cognitive biomarkers, voice biomarkers and physiological biomarkers have been developed to facilitate early disease diagnosis and treatment planning.

Among these, voice biomarkers have recently caught attention, offering a new possibility to diagnose diseases based on speech impairment and analysis. Notably, in Parkinson’s disease, voice disorders affect up to 89% of patients, and vocal biomarkers can detect early-stage changes in voice features in up to 78% of early Parkinson’s cases.

It is worth noting that the slight changes in the voice pattern and speech issues are considered as a primary sign of diseases in humans. This voice analysis can help to detect diseases at early stages, specifically neurological conditions and chronic conditions, where a patient may witness voice impairment. Owing to its non-invasive nature, voice biomarkers are increasingly being adopted to monitor neurological conditions, such as dementia and cognitive impairments. As more market players continue to increase their initiatives for the development of advanced digital biomarkers, we believe that the vocal biomarkers market will remain progressive in the future.
