Segment-based Melody Matching for Query By Singing/Humming

Blog Article

Dryer Corner Cover Segment-based melody matching approaches are proposed to solve the problems of pitch instability, tempo inconsistency, and puff noise of singing/humming in Query By Singing/Humming system.Instead of comparing frame by frame from the beginning and trying different scaling ratio, our segment-based approaches reduce the computation complexity by jumping to the possible segment boundary and using the segment ratio as scaling ratio.Our methods predict segment boundary candidates in query singing/humming and songs in database by detecting the abrupt change of pitch curve, match segment pair, scale Graveur-Decoupeur Laser each segment linearly and calculate the distance.

The top 10 recognition rate of our method can reach 70.6%.Our method reduce computational load and performs better in situations of puff noise and inconsistent tempo than popular global Linear Scaling method.
