Abstract

The invention discloses a twin network-based audio content consistency monitoring method and system. The method includes acquiring an audio signal; performing data segmentation on the audio signal to determine multiple groups of segmented audio signals; extracting each group The frequency domain feature of the audio signal after the segmentation; the acquisition takes the frequency domain feature as input, and the distance value of the frequency domain feature is output to establish an audio twin network model; according to the frequency domain feature and the audio twin The network model determines the distance value of the frequency domain feature; judges the size of the distance value and the distance threshold, and determines whether the content of the audio signal is consistent; when the content of the audio signal is not consistent, an alarm is output Signal. The invention provides a twin network-based audio content consistency monitoring method and system, which improves the accuracy and real-time performance of audio monitoring.

Description

Technical field [0001] Technical Field The present invention relates to audio analysis, more particularly to a method and an audio content integrity monitor system twin Network. Background technique [0002] The main objective to monitor the consistency of the audio content is distinguished from the physical characteristics of the audio content of agreement and disagreement audio, the audio-related technologies in multiple business areas have applications, including music search, advertising monitoring broadcast, audio broadcast monitoring Wait. Mainstream audio content related to the consistency of monitoring algorithm includes two aspects: similarity measure audio feature selection and audio features. Common audio features include audio waveform in the time domain, the frequency domain MFCC, short time Fourier transform coefficient. Time-domain waveform contains the most comprehensive audio information, but because it contains a lot of common audio information, audio for a part...
