Embodiment 1

[0038] Embodiment 1: as Figure 1-4 As shown, a sound identification system for broadcast monitoring, including

[0039] The signal processing module is used to process the target broadcast signal to obtain the audio signal in the target broadcast signal;

[0040] The threshold comparison module is used to filter out signals whose amplitude is lower than the threshold value in the audio, and complete the conversion from analog signals to digital signals;

[0041] The central processing unit is used to control the threshold value of the threshold comparison module, measure and calculate the frequency of the input signal, and judge whether the target audio signal is voice or music according to the threshold value and signal frequency, and the central processing unit can collect data information in real time;

[0042] The data storage module is used to store the data information collected by the central processing unit;

[0043] The result output module is used for outputting a...

Abstract

The invention discloses a sound discrimination system and method for broadcasting supervision. The system comprises a signal processing module for processing a target broadcasting signal and obtaining an audio signal in the target broadcast signaling, a threshold comparison module for filtering a signal whose amplitude is lower than a threshold value in an audio and completing the conversion from an analog signal to a digital signal, a central processor for controlling the threshold value of the threshold comparison module, calculating a frequency of an input signal, judging whether voice or music is in the target audio signal according to the threshold value and the signal frequency, and collecting data information in real time, a data storage module for storing the data information collected by the central processor, and an result output module for outputting and displaying a corresponding result. The sound discrimination system of the invention is almost realized by only using hardware, the cost is low, the feasibility is high, and very few software resources are occupied.

Description

technical field [0001] The invention relates to a sound identification system and method for broadcast monitoring, belonging to the fields of audio processing and broadcast monitoring. Background technique [0002] The monitoring of radio programs has always been a problem that our country attaches great importance to. How to accurately distinguish whether it is voice or music in the radio audio has always been a problem that radio monitoring needs to solve. [0003] The discrimination of human voice and music has its special application environment. On the one hand, the target audio signal requires only speech or only music. On the other hand, it is not necessary to know the specific content of the audio, but it needs to be judged in real time. [0004] Existing human voice and music discrimination technology, one is to start from the feature parameters of the extracted audio signal, and use the difference between the feature parameters when there is a human voice in the a...
