Method and system for analyzing personalized information and audio data for mini-mental state examination

Abstract

The invention discloses a method and a system for analyzing personalized information and audio data for mini-mental state examination. The method includes acquiring the personalized information of testees, allowing the testees to complete questions specified by the MMSE (mini-mental state examination), simultaneously recording speaking audio frequencies, extracting acoustic characteristics of the voice audio frequencies for pathological characteristics and representing the acoustic characteristics by the aid of high-order statistics; reducing redundancy of the characteristics by the aid of characteristic selection processes; fusing the acoustic characteristics with reduced dimensions and the personalized information of the testees with one another to obtain personalized characteristics; building pathological models of speaking conditions and mini-mental state examination cognition relations of the testees by the aid of the acquired data and analyzing the personalized information and the audio data by the aid of cross validation processes. The method and the system have the advantages that optional intrusive therapy can be omitted, physical states of the testees can be predicted only by means of analyzing relations between the acquired data and the pathological models, accordingly, the examination time and money can be saved, suffering experienced by the testees in examination procedures can be relieved, and influence of subjective judgment of doctors on results can be reduced.

Description

Technical field [0001] The invention belongs to the field of digital medical treatment, and specifically relates to a method and system for analyzing personalized information and audio data for a simple mental state scale. Background technique [0002] Nervous system disorders, including Alzheimer's disease, Parkinson's disease, small vessel disease, stroke and other similar diseases, are mostly caused by damage to the brain, spinal cord, and cranial nerve cells that cause changes in the body. The various organs and main manifestations of the human body are directly or indirectly under the regulation and control of the nervous system. Therefore, the nervous system is damaged. The main manifestations are difficulty in normal, clear and effective pronunciation and inconvenience of movement, and cognitive decline. Among them, language expression is an effective way of people's daily emotional communication. Damage not only affects the patient's physical and mental health, but also g...

Problems solved by technology

In the traditional sound signal analysis, binary classification training is generally performed by analyzing the relationship between sound characteristics and whether the subject has a disease. Only two results can be obtained: the subject is sick or not, and it is impossible to predict and judge the subject. Probability and degree of neurological disorders in patients
