  • Patent number: 10343287
    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 (S2) 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 (S4). 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.
