Starting with the actual multimedia English teaching, this paper analyzes the advantages of an intelligent learning environment as well as the application of virtual reality technology in English teaching. Comparing the traditional CAI courseware development with the courseware development based on virtual reality technology, it is proposed to use wavelet transform to decompose multimedia image resources, establish a static 3D virtual model library, transmit multimedia image files, and convert virtual reality-based network multimedia English teaching courseware. Propose a speech recognition algorithm based on DNN-HMM to help construct a multi-context virtual reality interaction mode. Examine the attitudes of students in different grades towards the use of virtual simulation technology in English teaching. Analyze the role of teaching timeliness in multimedia courseware and analyze the English classroom interaction in an interactive multimedia environment. In terms of student satisfaction, “your attitude towards the application of virtual simulation technology in English classes” is related to “the application of virtual simulation technology in English classes helps to open up new ways of English education, innovate new methods of education, and improve the carrier of education.” The correlation results are x2 =32.051, p =0.000, showing 0.01 level of significance. It indicates that students believe that using virtual simulation technology in teaching can innovate English teaching and that using multimedia courseware can also enhance the timeliness of English teaching. The university’s English teaching mode using multimedia courseware and interactive multimedia environments can enhance English performance, and 80.37% of students believe it has timeliness in teaching.
