摘要
介绍了运用哼唱进行检索的点歌系统.该系统从用户那里得到哼唱信息,把音频信息做特征提取、分割与分类,采用音变节奏算法查找出和输入内容相同或相似的乐曲.最后提出了有待继续研究的问题.
This paper presents a music query system by crooning. This system gets crooning information from the user, then abstracts the characters of the audio information, divides and classifies them, searches out the same music as or the similar ones to the inputs by alternative length rhythm algorism. Finally, raises some questions which need more study.
