Syntax is the core carrier of music and language. It is the knowledge of expression forms andrules that organize different semantic levels in time series. Previous studies have shown that musicaltraining is closely related to neural changes in language areas. Based on this, this study summarizes theneural basis of syntactic processing and compares the effects of music training on auditory processingin different groups. The results show that music training can improve the sensitivity of early syntacticprocessing, and also enhance the processing coding and information integration of language hearing.This study not only supports the view that music training can promote speech processing in OPERAframework, but also has very important practical significance and application value in the field ofeducation of special children and aging of speech perception ability.
