Direct broadcasting room singing identification method and device, server and storage medium

Abstract

The invention relates to a direct broadcasting room singing identification method and device, a server and a storage medium, and relates to the field of direct broadcasting. Firstly, a sound feature vector sequence is classified through a music sound classification model, and a classification result is obtained; if the classification result represents that the sound feature vector sequence comprises a music sound feature vector, an audio stream comprising the music sound feature vector is extracted from the direct broadcasting stream; then a human voice feature vector in the audio stream including the music voice feature vector is extracted; and finally, the human voice feature vectors are classified through a singing voice classification model to obtain a classification result. With the above analysis, the sound feature vector sequences are classified through the music sound classification model, and then the human voice feature vectors are classified through the singing sound classification model so that the obtained classification result is more accurate, and whether the anchor in the current direct broadcasting room is singing or not can be determined more accurately.

Description

technical field [0001] The present disclosure relates to the live broadcast field, and in particular to a singing recognition method, device, server, and storage medium in a live broadcast room. Background technique [0002] With the development of the mobile Internet, the development of live broadcast applications has made great progress and development. The anchor only needs to open a live broadcast room in the live broadcast application to perform live broadcasts. Listening to anchors sing songs is one of the performance methods that users of live broadcasting applications are interested in. [0003] In related technologies, traditional shallow model methods such as Gaussian Mixture Model (GMM) or Support Vector Machine (SVM) are often used for singing recognition, and the accuracy rate is low. Music, playing games or even leaving, that is, many contents that users are not interested in are mistakenly pushed to the audience. However, when the user enters the live broad...
