[0034] figure 2 A flow chart of an audio synthesis method provided by an embodiment of the present application is shown. The method includes the following steps.

[0035] Step 201, acquire the pitch value of the note in the target song.

[0036] The target song refers to a song to be synthesized. Optionally, the terminal obtains the score of the target song, and obtains the pitch value of the note from the score. Wherein, the score includes pitch values ​​of each note of the target song.

[0037] In a possible implementation manner, the terminal acquires pitch values ​​of all notes in the target song. In another possible implementation manner, the terminal acquires the pitch values ​​of some notes in the target song, where the part of notes refers to notes that need to be updated for pitch values. In a possible implementation manner, the note that needs to update the pitch value refers to the note whose number of sampling points is greater than a first threshold, and the...

Abstract

The embodiment of the invention provides an audio synthesis method and device, a terminal and a storage medium, and relates to the technical field of audio synthesis. The method comprises the steps of obtaining a pitch value of a note in a target song; updating the pitch value of the note by adopting a sliding sound generation function to obtain a first updated pitch value of the note, wherein the sliding sound generation function is used for enabling the pitch value of the sampling point in the note to present an increasing trend or a decreasing trend; and synthesizing the target song based on the first updated pitch value of the note. According to the technical scheme provided by the embodiment of the invention, during song synthesis, the pitch value of the first target note is updated through the sliding sound generation function, and during subsequent song synthesis, the song fragment generated based on the updated pitch value of the first target note can simulate the sliding sound effect of a person during singing so that the generated song fragment is more real.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data processing, and in particular to an audio synthesis method, device, terminal, and storage medium. Background technique [0002] Pitch refers to the height of a sound, which is determined based on the frequency of sound waves. Pitch is an important characteristic in audio synthesis. [0003] In related technologies, the terminal generates the pitch value of each note of the target song through a pitch generation model, and then the pitch value of each note is processed by an acoustic model to obtain an acoustic feature, and finally the target song is generated based on the acoustic feature. [0004] In the related art, the pitch value generated by the pitch generation model is unnatural, so that the target song generated based on the pitch value is not realistic enough. Contents of the invention [0005] Embodiments of the present application provide an audio synthesis ...
