Abstract

The embodiment of the invention discloses a method and device for adjusting a noise reduction model of audio equipment. The method comprises the steps: acquiring to-be-tested audio collected by target audio equipment; determining feature information of the to-be-tested audio; adjusting parameters of an audio noise reduction model based on the feature information; and in response to the received user voice signal collected by the target audio device, performing noise reduction on the user voice signal by using the audio noise reduction model after parameter adjustment. According to the embodiment of the invention, the use environment, use habits and other characteristics of the to-be-tested audio recognition user are integrated, the parameters of the audio noise reduction model are dynamically adjusted for different characteristics, and the calculation amount of the model is dynamically controlled on the basis of ensuring the noise reduction performance, so that the consumption of a CPU is reduced, and the power consumption is reduced.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a method, an apparatus, a computer-readable storage medium, and an electronic device for adjusting a noise reduction model of an audio device. Background technique [0002] Echo cancellation is an important part of speech signal processing. Existing technologies focus on enhancing echo cancellation performance and obtaining better echo suppression effect. In productized applications, different application scenarios are not differentiated. With the promotion of AI, the voice function has been given to more scenes, the echo scene has also changed from the original single-channel sound source to a stereo sound source or even a multi-channel sound source, and the number of signal acquisition microphones has also changed from one to multiple The processing complexity of the microphone array and the echo scene is doubled, which brings more computing resource requirement...
