Method and device of evaluating label quality of pitch information and storage medium

Abstract

The invention discloses a method and a device of evaluating label quality of pitch information and a computer-readable storage medium, and belongs to the technical field of information processing. Themethod includes: obtaining lyric information and the pitch information of a target song, wherein the lyric information includes a playing starting time point and continuous-playing duration which areof each sentence of lyrics in multiple sentences of lyrics of the target song and in playing duration of the target song, and the target song is a song of which the label quality of the pitch information is to be evaluated; and then evaluating the label quality of the pitch information of the target song on the basis of the playing starting time point and the continuous-playing duration of each sentence of lyrics in the multiple sentences of lyrics. Therefore, in the embodiment of the invention, the pitch information of labels can be inspected through the lyric information of the song, and thus an evaluation result is obtained; and compared with methods of manual inspection in the related art, the method of the invention saves manpower and time, also eliminates, at the same time, label errors caused by human factors, and improves accuracy of an evaluation result.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method, device and storage medium for evaluating the marking quality of pitch information.
