Classifier integration-based teacher classroom instruction identification method and system thereof

The invention discloses a classifier integration-based teacher classroom instruction recognition method and a system thereof, and the method comprises the steps: obtaining the to-be-recognized voice of a teacher in a classroom teaching process, carrying out the preprocessing of the obtained to-be-recognized voice, obtaining an audio segment set, carrying out the content recognition of the audio segment set, obtaining a text set, performing content attribute extraction on the text set to obtain a feature vector set, and finally inputting the feature vector set into a preset integrated classifier to obtain an instruction classification result corresponding to voice to be recognized, wherein the preset integrated classifier is integrated by a plurality of base classifiers, and the feature vector set of voice training data is used as a training sample, and the instruction classification result corresponding to the voice training data is obtained through sample label training. According to the method and the devic
