Abstract

The embodiment of the invention provides an audio-based personalized recommendation method and device and a mobile terminal, and the method comprises the steps: training an audio recognition model according to an audio sample set, and enabling the audio recognition model to be obtained through the cascade connection of a convolutional neural network and a recurrent neural network; acquiring a target audio feature of the target user; inputting the target audio feature into the audio recognition model to obtain a target audio vector; obtaining a target object from a candidate object list according to the target audio vector; and recommending the target object to the target user. According to the invention, the target audio vector (sound feature) can be obtained through the audio recognitionmodel to recommend the sound liked by the user to the user, which is helpful for improving the success rate of recommendation.

Description

technical field [0001] The present invention relates to the technical field of audio recognition, in particular to an audio-based personalized recommendation method, device and mobile terminal. Background technique [0002] Radio stations provide information to users through audio. For example, a car radio system can facilitate drivers to obtain road conditions, or music, or other information. In practical applications, it is also possible to make personalized audio recommendations to users, that is, to find anchors similar to the user's favorite anchors from the anchor list. [0003] In the prior art, it is usually possible to perform personalized audio recommendation based on the anchor's basic information, where the basic information includes: anchor's gender, age, program type, and so on. Specifically, at first, obtain the gender, age, and program type of the anchor with more historical listening times from the user's historical listening records as target information; ...
