In this study, speech recordings were analyzed using an artificial intelligence-based computer software program designed to identify speech patterns typical of the early stages of illness.

Data show that both approaches were successful in identifying records of participants with Alzheimer’s disease with an accuracy of 86% to 89%.
“The results of our study can create an opportunity to build new tools to identify the risk of Alzheimer’s disease using only the voice features obtained from everyday conversations on the phone.” Is writing.
This approach enables early detection and diagnosis of dementia, including Alzheimer’s disease and dementia, in the sense that the tool can be used not only by medical professionals but also by the general public at home, “they write. ing.
