摘　　要：为了提高英语发音错误自动校正系统的校正准确度,提出基于DTW算法的英语发音错误自动校正系统设计。依托语音识别传感器优化设计和发音识别处理器改进设计,完成系统的硬件设计;基于英语发音采集程序设计和提取英语发音错误信号参数,完成系统的软件设计。在DTW算法基础上,实现了英语发音错误自动校正系统设计。测试结果表明,基于DTW算法的英语发音错误自动校正系统相比于传统校正系统,英语发音校正的准确率提升了36.53%。A design of DTW algorithm based automatic correction system for English pronunciation mistakes is proposed to improve the calibration accuracy of the automatic correction system for English pronunciation mistakes. The hardware design of the system is completed based on the optimized design of speech recognition sensor and the improved design of pronunciation recognition processor. The software design of the system is completed based on the design of English pronunciation collection program and the extraction of English pronunciation mistake signal parameters. The design of automatic correction system for English pronunciation errors is realized based on DTW algorithm. The testing results show that the English pronunciation correction accuracy of the DTW algorithm based automatic correction system for English pronunciation mistake is 36.53% higher than that of the traditional correction system.
