An array surface electromyography-based pronunciation function evaluation system, the system comprising a lower computer and an upper computer, wherein the lower computer is used to obtain facial and neck myoelectric signals during a pronunciation process by means of array myoelectric electrodes, and transmit the facial and neck myoelectric signals to the upper computer; the upper computer is used to analyze the physiological correlation between change features in the facial and neck array myoelectric signals during the pronunciation process and a pronunciation function, establish a three-dimensional dynamic energy distribution map of facial and neck muscle movements during the pronunciation process, obtain dynamic visualized spatiotemporal information of pronunciation muscle groups, extract myoelectric feature values, establish a standardized database of the facial and neck myoelectric feature distribution of a normal pronunciation function, and employ template matching and a differential analysis algorithm to analyze the abnormal function conditions of the pronunciation muscle groups and the degree of damage. The present pronunciation function evaluation system is capable of more completely and objectively analyzing the electrophysiological characteristics of the pronunciation muscle groups during a pronunciation process, and achieving the real-time, objective and accurate evaluation of the pronunciation function.
