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 6):
A noise reduction system for a robot having a head and a servo for controlling the head to rotate, the head being provided with a microphone array having a noise suppression area and a sound source enhancement area, the system comprising a processor and a memory storing instructions executable for the processor, wherein the instructions function as:\n a position angle obtaining module configured to position a far-field sound source to obtain a position angle of the far-field sound source with respect to the microphone army; a target rotation angle calculation module configured to calculate a target rotation angle basing on the position angle and an initial rotation angle of the servo; a rotation control module configured to control the servo to rotate the target rotation angle to align the microphone array with the far-field sound source; a determination module configured to determine whether the sound source enhancement area is aligned with the far-field sound source basing on the position angle, the initial rotation angle, and the target rotation angle; and a changing module configured to change the noise suppression area currently aligned with the far-field sound source to the sound source enhancement area, in response to the sound source enhancement area being not aligned with the far-field sound source.
