Abstract

The application discloses a method and a device for determining the pitch deviation of audio content. The method includes: collecting the singing voice of the user when singing a song; adjusting the rhythm of the singing voice to be consistent with the standard rhythm of the song to obtain a human voice fundamental frequency sequence with a standard rhythm; determining the human voice fundamental frequency sequence according to the human voice fundamental frequency sequence. The fundamental frequency value, start time and end time of each singing voice in the sound fundamental frequency sequence; determine the user pitch of each singing voice according to the starting time, end time and the fundamental frequency value of each singing voice ; According to the user pitch of each singing voice and the pitch template corresponding to the song, determine the pitch difference between the user pitch and the standard pitch at each same time point, and obtain a pitch difference sequence. The purpose of determining the pitch deviation of the user's singing audio content is achieved, and then the technical problem of inaccurate pitch in the output audio due to the inaccurate pitch caused by the user's inability to sing the song is solved.

Description

technical field [0001] The present application relates to the technical field of sound processing, in particular, to a method and device for determining the pitch deviation of audio content. Background technique [0002] With the improvement of people's living standards, people's pursuit of cultural and entertainment life also increases, and thanks to the rapid development of communication and information technology, the music function has become an essential application in terminals such as computers or mobile phones. More and more music products with KTV functions appear in the user's terminal, most of which play the accompaniment according to the music selected by the user and display the subtitles along with the music accompaniment, and the user responds according to the font color prompts or other marking prompts on the displayed subtitles The singing time of the lyrics, until the completion of the whole song; so that users can obtain a singing experience similar to tha...
