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 11):
A terminal device for noise reduction, comprising:\n one or more processors; a memory; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs comprises; instructions for positioning a far-field sound source to obtain a position angle of the far-field sound source with respect to the microphone array; instructions for calculating a target rotation angle basing on the position angle and an initial rotation angle of the servo; instructions for controlling the servo to rotate the target rotation angle to align the microphone array with the far-field sound source; instructions for determining 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 instructions for changing 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.
