ETRI Completes Tablet-Based App Development
Image-video analysis research is also in progress
“Monitoring possible via smart device”
An artificial intelligence (AI) technology has been developed that can analyze the voices of the elderly and predict mild cognitive impairment, a pre-dementia stage, at an early stage.
The Electronics and Telecommunications Research Institute (ETRI) announced on the 1st that it has developed the world’s first Alzheimer’s disease prediction AI that combines a large language model (LLM) with voice and text analysis technology.
Speech production is a complex process involving cognitive functions such as memory and attention, language production functions such as phonetics, syntax, and semantics, and speech motor functions such as breathing, articulation, and vocalization. Analyzing this can help determine the decline in cognitive, language, and motor abilities that occur in patients with mild cognitive impairment or dementia.
The research team has also completed the development of a tablet-based app that predicts high-risk groups for mild cognitive impairment through voice utterances, and plans to improve the model by conducting verification tests at senior welfare centers in cooperation with the Korea Electrotechnology Research Institute.
The research team is developing a multimodal large-scale language model that can analyze and process not only voice and text but also images and videos, and is conducting follow-up research.
ETRI Senior Researcher Kang Byeong-ok said, “Compared to the method of visiting a public health center to receive a screening test, the conversation-based test method using a smart device has the advantage of enabling continuous and periodic monitoring,” adding, “It will contribute to the prevention and early diagnosis of dementia.”
