Embodiment Construction

[0040] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0041] Since during the call, the audio information collected by the terminal device is not only the voice information spoken by the caller, but also some noise signals in the environment where the caller is currently located, before transmitting the collected audio information , it is necessary to perform noise reduction processing to obtain clear voice information, so that the user...

Abstract

The invention is suitable for the technical field of communication, and provides a training method of an audio signal noise reduction model, an audio signal noise reduction method and equipment, and the audio signal noise reduction method comprises the steps: converting a currently collected audio signal with noise into an audio vector with noise; and inputting the audio vector with noise into a trained audio signal noise reduction model for noise reduction processing to obtain a noise-reduced audio signal. According to the method, the audio signal noise reduction model directly extracts the feature information used for distinguishing the audio signal and the noise signal based on the noise frequency vector corresponding to the noise frequency signal, and performs noise reduction processing based on the extracted feature information, so that the audio signal and the noise signal corresponding to the noise frequency vector can be accurately separated; the noise reduction effect of the audio signal with noise is improved, the audio quality is improved, and the voice call quality is further improved.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to a training method for an audio signal noise reduction model, an audio signal noise reduction method and equipment. Background technique [0002] The audio signal collected by the terminal device usually contains noise, and when the audio signal is further processed, it is usually required to perform speech noise reduction. Speech noise reduction is an effective processing technology for noise problems. Its purpose is to eliminate the influence of noise, improve speech clarity, and improve speech quality. [0003] For example, during a voice call, the audio signal collected by the terminal may contain environmental noise, other people's voices, etc. Before encoding and transmitting the audio signal, the terminal usually needs to perform voice noise reduction processing on the audio signal to obtain pure voice. Signal. The pure speech signal refers to ...
