Embodiment Construction

[0037] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0038] see figure 1 , the control method of the sound source localization of the robot of the present invention, wake-up identification, comprises the following steps:

[0039] In step S1, the array microphone continuously detects the sound source and obtains the sound signal; the array microphone includes a microphone for receiving the sound signal and a plurality of microphones for receiving the sound direction signal.

[0040] Step S2, matching the detected sound signal with the pre-stored offline voice command, and the matching is a wake-up command; the specific steps of this step are: matching the detected sound signal with the preset offline voice command, If the matching is successful, it is determined to be a wake-up instruction, and then proceed to step S3; if the matching is unsuccessful, then return to...

Abstract

The present invention discloses a control method of robot sound source positioning and awakening identification and a control system of robot sound source positioning and awakening identification. The method comprises the following steps of using an array microphone to detect a sound source continuously, and obtaining a sound signal; matching the detected sound signal and a pre-stored off-line voice command into an awakening instruction; sending the awakening instruction to a robot head MCU, and awakening the head MCU; using the head MCU to awaken a main controller, and sending a sound source direction signal to the main controller; after the main controller sends out the instruction to the head MCU, turning a robot head to a sound source direction, and waiting for other instructions. According to the present invention, the direction identification and the voice awakening are combined together, so that the man-machine interaction can be improved very well, the main controller can be in a standby state as much as possible, the power consumption is saved, and the use time is prolonged.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a control method for sound source localization and wake-up identification of a robot and a control system thereof. Background technique [0002] The world that robots face is a world that can provide complex and changeable information. To make a robot serve humans, it needs to have corresponding information acquisition methods and processing methods for various application environments, and it also needs to be able to respond to changes in the environment. Make different decisions, and robots generally input external environmental information through sensors. [0003] Robots often need visual sensors and auditory sensors as sound direction discrimination devices in agent work to determine the direction of the sound source, thereby controlling the direction of the robot's next movement. Present sound discriminating device can only discriminate the existence or general direction of...
