The Design of Automatic Correction System for Spoken English Pronunciation Errors Based on Phonemes

Abstract

The existing automatic correction system of oral English pronunciation errors has the problem of poor correction effect, in order to solve these problems, an automatic correction system based on phoneme is designed. The hardware design of the system includes architecture, audio signal modulator, demodulator, audio coUector and eontroller, The software design includes audio acquisition of spoken English pronunciation, speech signal matching flUer processing, oral pronunciation error detection and oral pronunciation error correction. Through the design of hardware and software of the system, the automatic correction system of spoken English pronunciation errors based on phonemes is realized. The experimental results show that: compared with the existing automatic correction system of spoken English pronunciation errors, the automatic correction system of spoken English pronunciation errors designed in this paper greatly improves the correction effect, which fully shows that the designed system has better application performance.
