Abstract:
A robot voice direction-seeking turning system and method. The robot voice direction-seeking turning system employs a voice activity detection unit ( 1 ) that detects a received voice signal to determine whether or not a voice signal transmitted by a user (S 2 ) is present; a direction-seeking angle for the voice signal is calculated by a voice direction-seeking unit ( 3 ), and a voice direction-seeking turning unit ( 4 ) is employed to drive a robot to turn towards the direction of the sound source of the voice signal on the basis of a direction-seeking angle (S 4 ). Employment of the robot voice direction-seeking turning method allows accurate acquisition of a valid voice signal transmitted by the user, thus increasing signal-to-noise ratio and the accuracy of voice recognition.

Claim (Index 17):
A robot voice direction-seeking turning method, applicable to the robot voice direction-seeking turning system of  claim 10 , wherein: comprising the following steps of:\n S 1 . acquiring and storing the sound signal; S 2 . detecting whether a voice signal is present in the sound signal, if yes, executing Step S 3 , if not, executing Step S 1 ; S 3 . acquiring the location information of the sound signal; S 4 . extracting the sound signal corresponding to the location information based on the location information, and performing calculation based on the sound signal corresponding to the location information, to obtain the direction-seeking angle; S 5 . driving the robot to turn a main interface thereon to the direction of the sound signal based on the direction-seeking angle.
