Title:
SPEECH ENHANCEMENT METHOD AND APPARATUS, AND DEVICE AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/105571
Kind Code:
A1
Abstract:
A speech enhancement method and apparatus, and a device and a computer-readable storage medium. The method comprises: collecting a speech signal by means of a microphone array, and converting the speech signal into a frequency-domain observation signal, wherein the speech signal is a time-domain observation signal (S10); inputting the frequency-domain observation signal into a first super-directivity beam former in a generalized sidelobe canceler, so as to determine a reference speech signal output by the first super-directivity beam former (S20); inputting the frequency-domain observation signal into a second super-directivity beam former in the generalized sidelobe canceler, so as to determine a noise signal corresponding to the speech signal (S30); and determining, on the basis of the reference speech signal and the noise signal, a speech enhancement signal corresponding to the speech signal (S40). By means of the method, a speech signal from a target orientation can be effectively enhanced, noise interference can be better removed, and the accuracy of a reference speech signal and a noise signal can be effectively improved, such that the accuracy of a speech enhancement signal can be further improved.
