摘要
提出了一个通过哼唱曲调从音乐库中搜索出所需歌曲的方法。由于在哼唱中引起的误差是不可避免的,所以应该考虑留有一定的冗余度。为了适应人们的哼唱习惯,给出了一个新的曲调表示法和新的分级匹配方法。详细描述了检索处理和数据库处理的算法。新的方法在实验评估中发挥了很高的效率。
In this paper,we present a solution for querying desired songs from music database by humming a tune. Since errors are inevitable in humming, tolerance should be considered. In order tomatch people s humming habit, a new melody representation and new hierarchical matching method are proposed in this paper. Query processing and database processing algorithm are also described in detail. The proposed solution achieves high performance in experimental evaluation.
