Embodiment Construction

[0028] The technical solution of the embodiment of the present application is applicable to the application scenario of repeated audio detection. By adopting the technical solution of the embodiment of the present application, repeated audio data can be detected from the audio data set more accurately and efficiently.

[0029] Audio data storage and audio data processing are common processing contents in the technical field of digital audio processing. In the field of digital audio processing technology, users usually use multiple means to collect the audio they need to process, so the same audio is often collected repeatedly due to different means, and the audio data collected repeatedly is for audio data storage and audio data processing. Will bring unnecessary waste of resources. Therefore, screening or detecting duplicate audio data from a large amount of audio data and eliminating them is a key process for improving audio data processing efficiency.

[0030] At present, ...

Abstract

The invention provides a repeated audio detection method, apparatus and device, and a storage medium. The method comprises the steps of obtaining audio features of audio data in a to-be-detected audiodata set; determining a similarity influence sequence between every two pieces of audio data according to the audio features of each piece of audio data in the to-be-detected audio data set, whereinthe similarity influence sequence comprises the contribution degree of each feature dimension of the audio features of the two pieces of audio data for measuring the similarity of the two pieces of audio data; for every two pieces of audio data in the to-be-detected audio data set, determining respective weighted audio features of the two pieces of audio data according to respective audio featuresand a similarity influence sequence between the two pieces of audio data; and detecting repeated audio data in the to-be-detected audio data set on the basis of the similarity between the weighted audio features of every two audio data in the to-be-detected audio data set. By adoption of the scheme, repeated audio data can be detected more accurately.

Description

technical field [0001] The present application relates to the technical field of digital audio processing, and in particular to a repeated audio detection method, device, equipment and storage medium. Background technique [0002] With the development of information technology in the direction of digitalization and intelligence, the amount of audio data generated and stored has increased dramatically. Repeated audio data will cause serious waste of resources in the storage and processing of audio data. [0003] Therefore, detecting repeated audio data from audio data is the key to saving audio data storage space and improving audio data processing efficiency, and it is also an urgent problem to be solved in the audio data processing process. Contents of the invention [0004] Based on the above requirements, the present application proposes a repeated audio detection method, device, equipment and storage medium to detect repeated audio data from audio data. [0005] In o...
