Time is Brain

BrainTalk is a software-based stroke prediction, detection and characterization tool that uses voice feature analysis to identify stroke earlier and thus reduce its incidence and negative consequences.
With effective but time-dependent treatments available, BrainTalk is designed to help stroke patients identify their condition and alert help fast. 


Early Detection Saves Lives

The weakest link in the stroke care pathway is awareness and early detection. Of approximately 1.5M stroke cases in developed countries each year, more than 70% do not reach medical facilities in time for optimal,

often life-saving treatment. 
The result: In the US, stroke is the number one cause of serious long-term disability and the number three cause of death. It is associated with annual costs of $70B and a personal and emotional burden to individuals and families that goes far beyond the financial costs.
Clearly, there is a critical need for a highly accessible tool able to alert at-risk individuals and care providers when a stroke occurs, so that they can reach medical facilities in time for optimal treatment.


The Solution

Voice changes are a primary warning sign of stroke, which can be detected, monitored and characterized. BrainTalk harnesses the information found in voice to provide an early trigger for the existing stroke care pathway.


BrainTalk’s algorithm is the product of a collaboration between neuropsychology experts at Israel’s National Institute for the Rehabilitation of the Brain Injured (NIRBI) and the leaders in machine learning technology at US-based predictive analytics company SentiMetrix.
