The invention discloses an audio data classification method, device and equipment and a storage medium, and the method comprises the steps: in response to an audio classification instruction, obtaining to-be-classified audio data; performing audio detection on the to-be-classified audio data frame by frame to obtain the percentage of non-voice data in the to-be-classified audio data; obtaining a pre-classification result of the to-be-classified audio data according to the percentage, a special sound threshold and an invalid sound threshold; classifying the to-be-classified audio data accordingto a preset determination condition of sound classification corresponding to the pre-classification result to obtain a classification result of the to-be-classified audio data. By pre-classifying theto-be-classified audio data in the whole classification process, and correcting the pre-classification result in combination with the pre-classification result and the corresponding preset determination condition, the classification accuracy is improved, extra training, marking and other operations are not needed, and therefore the technical problems that an existing audio classification method is high in workload and not high in accuracy rate are solved.
Description
technical field [0001] The present application relates to the technical field of voice classification, in particular to a method, device, device and storage medium for classifying audio data. Background technique [0002] In audio apps, there are scenarios where users record audio, especially in audio social apps. Users hope to meet new friends through audio and socialize based on audio. However, the user's recording behavior is uncontrollable. For example, a new user just wants to try a certain function and does not speak during the recording. At this time, the audio card obtained is an "invalid" audio card without valid information, or in the APP platform. Special audio cards with small noises, noises, etc. If users always hear audio without valid information, it will affect the product experience. In order to improve the user experience, the APP platform needs to screen the audio data and clear the audio without valid information. During the screening process, the audio...
