The invention discloses a spoken English man-
machine conversation interaction training method and
system, and relates to the technical field of spoken English training, spoken English audio signals of a user are monitored in real time through a
microphone, and the
frequency spectrum information of the audio signals is refined into each frame of
spectrogram and
cepstrum coefficient feature vectors by using
Fourier transform and
feature extraction technologies; therefore, the voice
signal characteristics of the user can be completely captured; three core dimensions of
semantic similarity, grammatical structure similarity and fluency are incorporated into an evaluation model, a comprehensive oral English
training evaluation system is formed, a text sequence is generated by analyzing a
time sequence dependency relationship through a
convolutional neural network, and the oral English
training evaluation model of a
deep learning technology is combined, so that the oral English
training evaluation accuracy is improved. According to the method, the expressions of the user in the aspects of
semantics, grammar and fluency can be accurately measured, the oral
training level of the user can be comprehensively judged by the
system by comparing the comprehensive evaluation coefficient with the preset qualified threshold value, and a
personalized learning guide is provided according to a result.
