Abstract

The embodiment of the invention discloses a noise reduction method and device. The method comprises the following steps: training a time domain characteristic value and a target value of the trainingdata through a deep learning training model constructed based on a frequency domain; the server can send the obtained model parameters to the terminal device, so that the terminal device updates the parameters of the first voice noise reduction model after receiving the model parameters, and uses the updated first voice noise reduction model to perform noise reduction processing on voice information input by a user. According to the embodiment of the invention, parameters of a first voice noise reduction model in terminal device are updated by using model parameters obtained by training of a deep learning training model, the terminal device can use the model parameters obtained by training of the deep learning training model to perform noise reduction processing on the voice information input by the user, so that the voice information obtained by noise reduction processing is more accurate, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a noise reduction method and device. Background technique [0002] In real life, the voice information sent by the user usually contains noise, for example, the sound of the wind in the environment, the sound of a car, the sound of a machine running, and so on. When the user uses the voice device to make a call, these noises may affect the user's call quality, making the user's experience bad. For example, user A and user B communicate through a terminal device (such as a mobile phone). If the voice information sent by user A through mobile phone a contains a lot of noise, user B may not be able to obtain user A's information through mobile phone b. For example, the obtained voice information is not clear enough, or the voice information sent by user A cannot be obtained. [0003] Therefore, there is an urgent need for a noise reduction method to solve the ...
