A pronunciation function evaluation system based on array surface electromyography

Abstract

The invention belongs to the technical field of pronunciation evaluation, and in particular relates to a pronunciation function evaluation system based on array type surface electromyography. The facial and neck myoelectric signals, and transmit the facial and neck myoelectric signals to the host computer; the host computer is used to analyze the physiological correlation between the change characteristics of the face and neck array type myoelectric signals and the pronunciation function during the pronunciation process, and establish the pronunciation The three-dimensional dynamic energy distribution diagram of the facial and neck muscle movement during the process obtains the dynamic and visualized spatio-temporal information of the pronunciation muscles, extracts the EMG feature values, and establishes a normal pronunciation function facial and neck EMG feature distribution standardized database, using template matching and differentiation Analyze the algorithm to analyze the abnormal function of the articulation muscles and the degree of damage. A more complete and objective analysis of the electrophysiological characteristics of the articulation muscles during the articulation process, and a real-time, objective, and accurate assessment of articulation function.

Description

technical field [0001] The invention belongs to the technical field of pronunciation evaluation, in particular to a pronunciation function evaluation system based on arrayed surface electromyography. Background technique [0002] Speech is an important tool for human information exchange. It contains information such as people's feelings and emotions, and is an important manifestation of social communication ability. Voice communication is the basic function of human social survival, and the ability to make a sound without loss is the key to expressing one's emotions. When pronouncing, the airflow from the lungs passes through the larynx, and the muscles contract to make the cartilage move, and at the same time drive the vocal cords to relax or tighten, and the glottis opens or closes accordingly, thus producing sound. The difference in the pitch of the voice is caused by controlling the tightness of the vocal cords. The pitch is determined by the length, tension, mass and...
