METHODOLOGICAL APPROACH TO IMPROVING THE EFFECTIVENESS OF THE REHABILITATION PROCESS BASED ON THE ANALYSIS OF STREAMING SPEECH DATA

Abstract

Background. Prompt and effective rehabilitation of people with mental retardation through processing and analysis of streaming speech data is important for the timely response of medical decision support systems aimed at improving the condition of a person with disabilities. The purpose of this work is to present an original methodological approach that ensures increased efficiency and efficiency of assessing the rehabilitation process of people with mental retardation through the analysis of informative parameters of speech signals under audiovisual stimulation. Materials and methods. To achieve the stated goals, the work uses mathematical and statistical methods for processing and detecting amplitude, frequency and time parameters of speech signals, programming and mathematical modeling. Results. A scheme has been developed for forming an information subsystem for recording speech signals in a person with mental retardation, which includes various stages of processing and analyzing speech signals in order to form a set of informative significant parameters. Conclusions. A methodological approach to increasing the efficiency of the rehabilitation process through the use of original algorithms and programs for detecting and comparing significant parameters of speech signals before and after the rehabilitation process and adjusting the process through negative feedback is presented and substantiated.
