A speech-based system for the detection of Alzheimer's disease

The ELEKIN research group of the UPV/EHU-University of the Basque Country is developing biosignal analysis systems to help medical staff who make diagnoses.

Featuring among other projects is the automatic analysis of spontaneous speech: a smart, non-invasive diagnostic technique for the early detection of Alzheimer's disease.  Automatic Spontaneous Speech Analysis (ASSA) is one of the non-invasive techniques to help in detecting disorders relating to dementia. This methodology is based on the recording of patients while they are describing some experience in their own lives in a relaxed, leisurely atmosphere, and on the measuring of various parameters. For example, the pauses the patient makes when trying to remember the word he/she wants to say are measured. So the technique is carried out without altering or blocking the patient's abilities as he/she does not perceive the test as something stressful. This work has aimed to provide clinical professionals with tools enabling them to make diagnoses in a much less invasive way.
