Problems solved by technology

Due to the influence of human subjective factors, large deviations may occur. Therefore, the accuracy of the detection results obtained by this detection method for audio breakpoint detection is low.
However, the normal sound effects of some audio have intentionally designed sound effects similar to breakpoints, making it difficult to detect audio breakpoints, and the detection accuracy and recall rate are low

Abstract

The invention discloses an audio detection method and device, and a storage medium. The method comprises steps that pre-screening processing of a to-be-tested audio is performed to filter out candidate audio segments in the to-be-tested audio; the candidate audio segments are inputted into a trained local identification model to perform audio breakpoint detection to generate the detection result of the candidate audio segments, according to the detection result of the candidate audio segments, whether the to-be-tested audio has breakpoints is determined. The method is advantaged in that the candidate audio segments possibly having the breakpoints in the to-be-tested audio are screened out through pre-screening processing, the trained local identification model is then utilized to perform audio breakpoint detection, accuracy and the recall rate of audio breakpoint detection are improved, robustness of rhythm type pseudo breakpoints is improved, and thereby the audio breakpoints can be effectively detected.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio processing, and in particular to an audio detection method, device and storage medium. Background technique [0002] Breakpoints are a kind of error that often occurs in audio. Breakpoints will cause the sound of audio playback to be intermittent, or the sound will be lost, which will seriously affect the quality of audio. Therefore, breakpoint detection can be performed on audio to detect existing breakpoints Make repairs. [0003] At present, when detecting breakpoints in audio, it is generally to audition the audio through artificial hearing, subjectively judge whether there are breakpoints, and manually mark them, or identify the breakpoints through simple signal features. Due to the influence of human subjective factors, large deviations may occur. Therefore, the accuracy of the detection results obtained by this detection method for audio breakpoint detection is low. However, the...
