Patent number: 12154586Abstract: A computer-implemented method for suppressing noise from audio signal uses both statistical noise estimation and neural network noise estimation to achieve more desirable noise reduction. The method is performed by a noise suppression computer software application running on an electronic device. The noise suppression computer software application first transforms the speech signal in time domain into frequency domain before determining a statistical noise estimate and a neural network noise estimate. The noise suppression computer software application merges the two noise estimates to derive a final noise estimate, and determines and refines a noise suppression filter. The filter is applied to the speech signal in frequency domain to obtain an enhanced signal. The enhanced signal is transformed back into time domain.Type: GrantFiled: May 24, 2022Date of Patent: November 26, 2024Assignee: Agora Lab, Inc.Inventors: Jimeng Zheng, Bo Wu, Xiaohan Zhao, Liangliang Wang, Ruofei Chen
