Problems solved by technology

The production of the former requires a lot of labor and time costs, while the accuracy of the latter is not high, mainly because the original singing separation dry sound itself has a lot of incomplete spectrum and word swallowing. In the poor quality separation dry sound Forced alignment on the above, then the accuracy of the alignment result is also difficult to guarantee
To sum up, in the process of realizing the present invention, the inventor at least found that there is a problem in the prior art that the accuracy of the generated lyrics timestamp is not high

Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0054]Currently, there are two ways to generate lyrics files in the music library, which are manual fine-tagging and automatic generation based on the original vocal separation. The production of the former requires a lot of labor and time costs, while the accuracy of the latter is not high, mainly because the original singing separation dry sound itself has a lot of incomplete spectrum and word swallowing. In the poor quality separation dry sound It is difficult to guarantee the ac...

Abstract

The invention discloses a lyric timestamp generation method and device, equipment and a medium. The lyric timestamp generation method comprises the steps: obtaining multiple pieces of target acapella data corresponding to the same song; obtaining a target acoustic feature corresponding to each piece of target acapella data; determining starting time and ending time of each sentence of lyrics in each piece of target acapella data based on the target acoustic feature to obtain a first starting time and a first ending time; determining the starting time and the ending time of each word in each piece of target acapella data by using a target MFA model to obtain a second starting time and a second ending time; and determining a lyric timestamp of the song based on the first starting time, the first ending time, the second starting time and the second ending time corresponding to the multiple pieces of target acapella data. In this way, the finally determined lyric timestamp fuses the time determined based on the acoustic features of the multiple pieces of target acapella data and the time determined by the MFA model, and the accuracy of the lyric timestamp can be improved.

Description

technical field [0001] The present application relates to the technical field of speech processing, and in particular to a method, device, device and medium for generating a lyrics timestamp. Background technique [0002] Currently, there are two ways to generate lyrics files in the music library, which are manual fine-tagging and automatic generation based on the original vocal separation. The production of the former requires a lot of labor and time costs, while the accuracy of the latter is not high, mainly because the original singing separation dry sound itself has a lot of incomplete spectrum and word swallowing. In the poor quality separation dry sound It is difficult to guarantee the accuracy of the alignment result. To sum up, in the process of implementing the present invention, the inventor at least found that there is a problem in the prior art that the accuracy of the generated lyrics timestamp is not high. Contents of the invention [0003] In view of this,...
