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 10):
A robot voice direction-seeking turning system, comprising:\n a voice acquisition unit, for collecting a sound signal and store the collected sound signal; a voice activity detection unit, connecting to the voice acquisition unit, for detecting whether a voice signal is present in the sound signal, and outputting the detection result; a voice direction-seeking turning unit, connecting to the voice activity detection unit, when the detection result indicating that the voice signal is present in the sound signal, controlling the voice acquisition unit to obtain location information corresponding to the sound signal, and outputting the location information; and a voice direction-seeking unit, connecting to the voice acquisition unit and the voice direction-seeking turning unit respectively, for 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 a direction-seeking angle, and outputting the direction-seeking angle.
