Research on auxiliary training system of oral English pronunciation based on data extraction

Abstract

Due to the limitations of the language environment and other aspects, students generally have problems such as inaccurate English pronunciation in oral English learning. To solve the English pronunciation problem, an English oral pronunciation auxiliary training system based on data extraction is designed. With the help of the B/S three-tier structure, the system designs the overall framework of the system, including the data layer, business logic layer, and display layer. In the hardware design of the system, the collection, transmission, and processing of oral English pronunciation audio are realized with the help of pickup, audio Bluetooth chip, and programmable logic controller. Three business processing programs are designed, including a pronunciation audio input processing program, pronunciation audio data extraction program, and pronunciation auxiliary training program, to correct oral English pronunciation. The experimental results show that the system can improve students' oral English pronunciation and improve students' oral learning performance.
