Voice Analysis and Measurement of Pathophysiology : Technology to visualize disease by voice



Purpose of Research

We are researching technology to detect minute changes in voice associated with disease and visualize the disease in a non-invasive manner. Voice stress assessment technology has already been developed and has been
commercialized by several companies. It was also adopted as one of the ME-BYO Index promoted by Kanagawa Prefecture. Currently, we are conducting research on depression, dementia, and Parkinson's disease with a view to the aging society. Furthermore, we are looking for ways to utilize this technology in fields other than healthcare.

Subjects of Reseach

Development of voice biomarkers (stress, depression, dementia, Parkinson's disease, etc.)
Application of voice biomarkers (athlete mental care, etc.)
