Design of English Listening,Speaking,Reading and Writing Training System Based on Audio Analysis and Natural Semantic Analysis
In order to solve the problems of the extreme lack of English teaching environment in China and that most English teaching platforms in the market have not achieved ideal results,an English listening,speaking,reading and writing training system based on audio analysis and natural semantic analysis is designed.In terms of the contents,semantic analysis is carried out,and LDA(Document generation Model),which is popular in analyzing text similarity,is used to model the discrete data set.In terms of pronunciation,for the recognition of isolated words,DTW(Dynamic time integration)algorithm is applied to calculate the similarity between target speech and standard speech,and the pronunciation is evaluated on the basis of this.It provides students with a"comprehensive English ability learning system"for self-testing,so that students can complete systematic and standardized English training independently.
