Abstract

According to the first aspect of the invention, the invention provides a background music audio generation method and a device. The method comprises the following steps: acquiring an audio needing to be dubbed; acquiring beat information and melody information of the audio; dividing the audio into a plurality of sections based on the beat information; on the basis of the beat information and the melody information of each section, generating a background music section corresponding to the section; combining the plurality of background music sections to generate background music for the audio; and synthesizing a background music audio based on the audio and the background music. Therefore, according to the beat and melody of the input audio, the duade music section can be automatically matched, and the original duade music work which is highly matched with the input audio (such as human voice humming or rap) is synthesized from the duade music section.
