Document Type and Number:
WIPO Patent Application WO/2023/226592
Kind Code:
A1
Abstract:
Provided are a noise signal processing method and apparatus, and a storage medium and an electronic apparatus. The method is applied to a voice module, and the voice module comprises a plurality of microphones. The method comprises: for each of a plurality of microphones, acquiring audio data that is collected by the microphone, and converting the audio data into frequency domain data (S202); performing separation processing on a noise signal and a sound source signal in the frequency domain data, and obtaining a reference signal on the basis of frequency domain data which has been subjected to separation processing (S204); obtaining spliced data on the basis of the frequency domain data and the reference signal, and inputting the spliced data into a target model, so as to obtain a noise estimation signal (S206); and performing noise reduction processing on the frequency domain data according to the noise estimation signal, so as to obtain a sound source signal which has been subjected to noise reduction processing (S208).
