Abstract

The present invention provides a system and method for generating verbatim lyric files based on a K-means clustering algorithm, the method comprising: acquiring audio data and text that need to generate lyric files, and then dividing the audio data into at least one audio segment , performing Fourier transform on the audio segment to obtain the corresponding frequency domain segment, obtaining the energy distribution range value of the frequency domain segment in the frequency domain, using the K-means clustering algorithm to determine that the frequency change is obvious according to the frequency energy change difference value The time nodes in the audio data are combined with the text in the audio data, and the obtained time nodes are one-to-one corresponding to the text according to the sequence to generate the verbatim lyrics file. The above solution solves the problem of inaccurate word-for-word lyrics in the current lyrics file.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to a system and method for generating verbatim lyrics files based on a K-means clustering algorithm. Background technique [0002] K-means clustering algorithm is a typical distance-based clustering algorithm, which uses distance as the evaluation index of similarity, that is, the closer the distance between two objects, the greater the similarity. The algorithm considers that clusters are composed of objects that are close to each other, so the final goal is to obtain compact and independent clusters. [0003] Now when audio playback devices such as mp3 play song files, there is no word-for-word corresponding lyrics, and the word-for-word lyrics need to be manually produced. At present, through the audio detection file core speech intelligent recognition technology, it is possible to automatically generate verbatim lyrics for all songs. However, the existing lyrics subtitles canno...
