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.

A biomarker for clinical research

Paper-based cognitive assessments are slow, subjective and often coarse. Winterlight has developed a speech-based cognitive assessment that analyzes short snippets of speech and uses AI to objectively measure cognition via hundreds of vocal biomarkers in speech and language. Winterlight can support clinical trials and studies for a wide range of central nervous system disorders.

Tracking cognitive wellness in senior care

It is challenging to care for seniors with complex medical needs and frequently with cognitive impairments. Combined with your existing health data, we identify seniors at-risk of cognitive or functional decline. Our assessment can help you provide better proactive care at a time when it is most needed to have the greatest impact on the health and happiness of your residents.

Winterlight’s Healthy Aging Study

We are building better tools so that we can identify risk for dementia more quickly and at an earlier age. This will allow researchers to better understand the disease and work towards a cure. If you are healthy and 50 years or older in the Greater Toronto Area, we would like your help on learning the effect of the aging process on the brain.
