The invention relates to the technical field of English pronunciation learning, and discloses an AI (
artificial intelligence) English learning
system capable of correcting pronunciation. The
system comprises a multi-source voice acquisition layer, an acoustic feature analysis layer, a pronunciation quality evaluation layer, a correction decision generation layer and a
biological feedback execution layer. The multi-source voice acquisition layer captures a multi-channel
sound wave signal and a maxillofacial electromyographic
signal in real time when a user pronounces, and generates an original pronunciation
data stream; the acoustic feature analysis layer performs time-
frequency domain conversion on
original data, separates multi-scale acoustic features and constructs a three-dimensional feature
tensor; the pronunciation quality evaluation layer compares the
standard template library to output scores and phoneme offset vectors; the correction decision generation layer constructs a pronunciation error
topological graph and generates a correction
instruction set containing tongue position,
airflow and vocal cord parameters; and the
biological feedback execution layer synchronously monitors the physiological response and updates the weight of the
template library. According to the
system, accurate acquisition, analysis, evaluation, correction and dynamic optimization of pronunciation learning are realized, and the English pronunciation learning effect is improved.
