Abstract:
The present disclosure provides a noise reduction processing method, system and terminal device. In the present disclosure, a position angle of a far-field audio input sound source and a microphone array as well as a rotation angle of a head servo of a robot are obtained, and then a target rotation angle of the robot is calculated. The head servo of the robot is controlled to rotate according to the target rotation angle such that the robot moves along with the far-field sound source, and a beam area is changed according to the target rotation angle to enable a sound source enhancement area to process far-field audios. As a result, the noise reduction performance of the microphone array beam is effectively improved.

Claim (Index 4):
The method of  claim 3 , wherein the step of calculating the determination angle basing on the position angle and the Initial rotation angle comprises:\n determining whether the position angle meets a second preset condition: setting the determination angle as a sum of the position angle and the initial rotation angle, in response to the position angle meeting the second preset condition; and setting the determination angle as subtracting a group angle of the position angle from the initial rotation angle, in response to the position angle not meeting the second preset condition, wherein the group angle of the position angle equals to 360 minus the position angle.
