Claim 2:
3. The method according to claim 2, wherein the determining an azimuth of a target voice associated with the multi-channel sampling signals based on the spatial spectrum estimation result and a highest wakeup word detection score comprises:
determining an azimuth of a target main beam, the target main beam being a main beam, among the N1 beams, of a sampling signal corresponding to the highest wakeup word detection score;
determining at least one local maximum value point among the signal power strengths at the N2 candidate azimuths; and
determining the azimuth of the target voice based on the azimuth of the target main beam and the at least one local maximum value point.
