While the need is more urgent than ever, our core technology has been researched and developed for more than a decade. The foundational research began in a lab at the Cincinnati Children’s Hospital and Medical Center (CCHMC).  Dr. John Pestian and Dr. Tracey Glauser conducted research to determine whether machine learning algorithms could pick up small differences in a person’s language to identify which patients were at risk of suicide. First, they ran analyses on the largest ever collection of suicide notes, donated by bereaved families. Next, they refined the algorithms to analyze speech samples.
