An auxiliary communication system based on surface electromyography lip reading recognition, comprising: a training subsystem, used for collecting face and neck electromyography signals during lip movements via a high-density electrode array, increasing signal quality via a preprocessing algorithm, classifying lip movement types via a classification algorithm, selecting an optimal electrode number and an optimal position via a channel selection algorithm, establishing an optimal matching template between the electromyography signals and lip reading information, and uploading to a network terminal for storage; and, a detection subsystem, used for collecting, on the basis of the optimal electrode number and position selected by the training subsystem, electromyography signals at the optimal position during the lip movements, calling the optimal matching template, performing classification decoding with respect to the electromyography signals, recognizing the lip reading information, converting into corresponding speech and image information, displaying in real-time, and implementing lip reading recognition, thus greatly increasing the accuracy of lip reading recognition.
