The application discloses an audio scoring method, device, equipment and storage medium, belonging to the field of computer technology. The method includes: obtaining a plurality of vibrato segments corresponding to the fundamental frequency sequence of the audio to be scored; acquiring vibrato feature information of the fundamental frequency sequence corresponding to the plurality of vibrato segments, the vibrato feature information including at least spectrum distribution stability and sequence amplitude; The tremolo segment duration of a trill segment, and the frequency spectrum distribution stability and sequence amplitude of the fundamental frequency sequence corresponding to a plurality of trill segments are used to determine the trill scores of a plurality of trill segments. According to the vibrato scores and the number of vibrato segments of multiple vibrato segments, the audio vibrato score of the audio to be scored is determined, and based on the audio vibrato score, the audio to be rated is scored. In this way, on the basis of focusing on pitch in traditional scoring, attention is also paid to vibrato segments, which overcomes the problem that the scoring method in the prior art that only focuses on the pitch of the audio to be scored is too single, resulting in a relatively one-sided score.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to an audio scoring method, device, equipment and storage medium. Background technique [0002] With the development of network technology, more and more music software can provide singing modes, and in order to help users better grasp the singing skills of songs, they can also provide scoring functions to score the audio to be rated. [0003] Existing scoring methods usually compare the pitch sequence of the original audio and the pitch sequence of the audio to be scored, and score the audio to be scored according to the relevant matching algorithm. For example, the fundamental frequency sequence of the original singing audio and the fundamental frequency sequence of the audio to be scored can be extracted respectively by the fundamental frequency extraction method, and the fundamental frequency sequence of the original singing audio and the fundamental frequency sequen...
