Abstract

The invention discloses a playing scoring method which comprises the following steps: 1) firstly, segmenting the standard playing according to the beats; 2) secondly, recording the playing of a player, and segmenting the playing according to the beats; 3), matching the segments of the standard playing and the segments of the playing according to the beats; and 4) evaluating each segment of matchedplaying. According to the playing scoring method, the standard playing and the playing are segmented, and each segment is evaluated, and such a segment scoring method makes the scoring of the playingfine, the grading efficiency is higher, and the obtained scoring result is more accurate.

Description

technical field [0001] The invention relates to a performance scoring method. Background technique [0002] For the evaluation method of singing, the scoring system of karaoke is common at present. This scoring system calculates the difference between some simple physical characteristics between the performer's singing and the original sound (or data that can be regarded as the original sound) in the database, such as Compare the distance between the singing signal and the sampling point of the target signal, compare the distance between the sound level curves, compare the distance between the fundamental frequency sequences and other differences, and take these differences as the evaluation standard. [0003] This scoring system is only compared on the level of simple physical characteristics. When the user's singing and the original sound in the database have large differences in these physical characteristics, but they match relatively from the perspective of melody, kara...
