Monitoring cognitive impairment through speech

Winterlight has developed a tablet-based assessment that is fast, objective, and stress-free. By analyzing speech alone, we can detect cognitive impairment associated with dementia and mental illness. Our assessment can be used in life science research, senior care and clinical settings.

Vocal biomarkers for use in clinical trials

Existing neurological assessments are slow, subjective, and difficult to do remotely. Winterlight’s technology can extract speech-based digital biomarkers from short snippets of speech. The Winterlight Assessment is currently used in a dozen clinical trials to track changes and identify treatment responses. We support life science partners throughout their trials for site onboarding, data collection, speech analysis, and results interpretation.

Ratings Quality Assurance

We automate the review of clinical assessment administration and scoring in clinical trials. Using our speech analysis platform we provide fast, reliable auditing and analysis of clinical assessments.


Sign up to access our speech analysis API

We make clinically validated speech-based biomarkers easy to access and use. Our API can be used to receive analyses for speech data you have already collected, or to integrate with your app or device that continuously collects speech in order to receive fast results.

Participate in Winterlight studies

We are researching speech patterns in people of all ages to help us build better tools for disease detection and monitoring. This will allow researchers and clinicians to better understand the signs of neurological and psychiatric disease and work towards treatment and cures. We invite you to help us by participating in our research studies.
