Embodiment Construction

[0080] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0081] The inventors found that for audio distribution platforms (for example, fast video, music application APP, music website, etc.), user experience largely depends on the audio search hit rate and recommendation accuracy. In order to ensure the search hit rate and recommendation accuracy, it is necessary to accurately classify the massive audio on the platform and assign a comprehensive and reasonable label to each audio.

Abstract

The invention provides an audio labelling-processing method and device. The method comprises the steps that original audio signals are obtained; the original audio signals are discretized to obtain target audios; characteristics of the target audios are extracted through a timing-sequence convolutional neural network (CNN) to obtain characteristic vectors of the target audios; clustering analysisis conducted on the characteristic vectors to obtain different categories of original audios corresponding to the characteristic vectors; according to the different categories of the original audios corresponding to the characteristic vectors, keywords in titles corresponding to the original audios in the same category are extracted, and one or more keywords are selected from the keywords according to a predetermined rule to serve as audio labels of the category. By adopting the scheme, efficient and accurate audio classification is achieved, high-accuracy and comprehensive audio labelling isachieve, and accordingly the search hit rate and recommending accuracy of audios can be improved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio tagging processing method, an audio tagging processing device, a computer storage medium, and a computing device. Background technique [0002] With the development and popularization of network technology, a large number of aggregated audio distribution platforms have emerged, which can provide network users with personalized audio services, including uploading, searching, recommending, playing, downloading and other services. In order to make it easier for users to search and use audio, and to make audio recommendations that meet users' interests and needs, it is necessary to accurately classify the massive audio on the platform and assign comprehensive and reasonable tags to each audio. Existing audio tagging methods usually use manual annotation, or simply extract keywords from the title and explanatory text of a single audio as tags, which have low ...
