SPEECH ENHANCEMENT METHOD AND APPARATUS FOR DISTRIBUTED WAKE-UP, AND STORAGE MEDIUM

WIPO Patent Application WO/2023/246223

A1

A speech enhancement method and apparatus for distributed wake-up, and a storage medium, which relate to the technical field of smart homes. The method comprises: acquiring N pieces of frequency-domain data corresponding to N microphones of a microphone array, wherein the N pieces of frequency-domain data are obtained by means of performing a Fourier transform on speech data which is received by the microphone array (S202); determining a delayed addition beam and a delayed subtraction beam of the N pieces of frequency-domain data in each sound pickup direction among M sound pickup directions, so as to obtain M delayed addition beams and M delayed subtraction beams, wherein the N pieces of frequency-domain data all correspond to delayed addition beams and delayed subtraction beams in different sound pickup directions, N is an integer greater than 3, and M is an integer greater than 2 (S204); and inputting the signal amplitudes of the M delayed addition beams and the signal amplitudes of the M delayed subtraction beams into a speech enhancement model, so as to enhance target speech in the speech data by means of the speech enhancement model (S206).
