Problems solved by technology

[0002]In the system where the speaker and the microphone are coupled, due to the existence of the broadcasting system, the sound from the speaker to the microphone is picked up by the microphone and played by the speaker, and the loop continues. In the end, howling often occurs, which seriously affects the user experience, and even damages sound amplification equipment such as audio equipment.
[0003]At present, the commonly used methods of howling suppression are to suppress the howling after the howling is generated, for example, by using a trap filter to suppress the howling Control, this method has limited effect, and will also have a significant impact on the user's sense of hearing, reducing the user experience

Abstract

The invention discloses a howling suppression method, a related model training method and device, and a storage medium. The method comprises the following steps: acquiring a target audio signal; detecting the target audio signal by using the acoustic feedback model, and determining the maximum stable gain of the target audio signal, wherein the audio signal obtained by performing gain processing on the target audio signal by using the maximum stable gain can meet a preset howling suppression requirement; obtaining a target gain according to the maximum stable gain, wherein the target gain is not larger than the maximum stable gain; and performing gain processing on the target audio signal by using the target gain to obtain an output audio signal. According to the scheme, generation of howling can be reduced.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a method for suppressing howling, a related model training method, equipment, and a storage medium. Background technique [0002] In the system where the speaker and the microphone are coupled, due to the existence of the broadcasting system, the sound from the speaker to the microphone is picked up by the microphone and then played by the speaker, which is continuously looped, and eventually howling is often generated, which seriously affects the user experience, and even Destruction of sound amplification equipment such as audio equipment. [0003] At present, the commonly used methods of suppressing howling are to suppress the howling after the howling is generated, for example, by using a wave trap to control the howling. This method has limited effect and will also affect the user's hearing. have a significant impact on perception and degrade the u...
