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 8):
The system of  claim 6 , wherein the target rotation angle calculating module comprises:\n a determination angle calculating unit configured to calculate a determination angle basing on the position angle and the initial rotation angle; and a target rotation angle obtaining unit configured to calculate the target rotation angle basing on the determination angle.
