基于特征比对的音乐学唱系统设计与实现

Design and implementation of music learning system based on comparision of characteristics

为了弥补音乐教材的局限性和部分地区音乐教师资源不足的现状,将计算机自动评分引入音乐学习中,开发了一套基于特征比对的音乐学唱系统。与互联网上已有的商业音乐评分系统的区别在于系统的教育定位,主要体现在反馈评价模块的设计和实现上。系统通过旋律特征提取、相似度比对、音高数据分析来进行演唱自动评分,定位出错位置,估计出错原因,给予学习者详细的反馈意见和指导建议。应用案例研究结果表明,该系统具有实际应用价值。

To make up for the limitations of music teaching materials and the present situation of the lack of music teachers in some areas,the technology of computer grading was introduced into music study,a music learning system based on comparison of characteristics was developed.This system was different from existing business music grading systems on the Internet in terms of educational orientation which mainly embodied in the design and implementation of the feedback module.Through the imple-mentation of melody characteristics extraction,similarity matching,pitch analysis and so on,system could grade learners’sin-ging,locate the position of errors and estimate the causes of errors,then provide learners with detailed feedback and correct ad-vice.The application case results showed that this system could help learners efficiently in music study.
