Embodiment Construction

[0097] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0098] like figure 1 As shown, the present embodiment proposes the first speech signal denoising method, which may include the following steps:

[0099] S101. Obtain multiple voice signals collected by the microphone array, where the multiple voice signals include noise;

[0100] Wherein, the microphone array may be composed of multiple microphones. Each microphone in the microphone array can collect one voice signal.

[0101] It should be n...

Abstract

The invention discloses a voice signal denoising method and device. The method comprises the following steps: acquiring multiple voice signals collected by a microphone array, wherein the multiple voice signals comprises noise; carrying out sound source localization on the multiple voice signals, determine a sound source azimuth angle, and determine a voice signal located on a target azimuth angle as noise, wherein the angle deviation value of the target azimuth angle and the sound source azimuth angle is not smaller than a preset angle deviation threshold value; determining a corresponding target sub-band filter coefficient based on the angle deviation value of the target azimuth angle and the sound source azimuth angle; and performing denoising processing on the voice signal located on the target azimuth angle based on the target sub-band filter coefficient. According to the method, while the voice signal output by the target sound source is prevented from being influenced, effective de-noising processing of the collected multi-channel voice signal is realized, and the audio de-noising capability is effectively improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a voice signal denoising method and device. Background technique [0002] With the improvement of signal processing technology, speech signal denoising technology has been continuously improved. [0003] Currently, in the existing technology, voice collection equipment can be used to collect, denoise, and record the voice signal output by the target sound source in a specific place. [0004] However, the existing technology cannot effectively denoise the collected speech signal. Contents of the invention [0005] In view of the above problems, the present invention provides a voice signal denoising method and device that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows: [0006] A voice signal denoising method, comprising: [0007] Obtaining multi-channel voice signals collected by the microphone arr...
