Problems solved by technology

[0002] When the current movable and mechanically capable robot is working, due to the operation of the steering gear and / or motor, or the operation or cleaning of other objects (such as door opening operation, dishwashing operation, sweeping operation, etc.), it is inevitable Noise is generated, and if the user issues voice commands to the robot during this process, the noise will inevitably have a certain impact on the accuracy of the robot's speech recognition
Even if there is a noise reduction algorithm, it can only filter the steady-state noise, and it is difficult to filter out the changing and unpredictable noise during the working process of the robot
Another method is that the robot will stop the current action after detecting the user's voice, and continue the previous action after receiving the voice command, but this will inevitably reduce work efficiency

Embodiment 2

[0045] see figure 2 , figure 2 It is a structural schematic diagram of an embodiment of the robot voice command recognition device of the present invention. like figure 2 As shown, this embodiment includes:

[0046] The detection module 201 is used to detect the voice command sent by the user;

[0047] The detection module can continuously detect whether the user sends out a voice command, for example, when the user's voice is captured, it can be considered that the user is sending out a voice command.

[0048] A judging module 202, configured to judge whether the current voice command recognition accuracy rate is lower than a preset accuracy rate threshold;

[0049] Preferably, the preset accuracy rate threshold corresponds to the priority of the robot's current task execution; the higher the priority of the task execution, the lower the corresponding accuracy rate threshold. In this way, execution tasks with higher priority are less likely to be disturbed by voice co...

Embodiment 3

[0060] see image 3 , image 3 It is a structural schematic diagram of an embodiment of the robot device of the present invention. like image 3 As shown, the robotic device 300 includes:

[0061] at least one processor 310, image 3 Take a processor 310 as an example; and a memory 320 communicatively connected with at least one processor 310; wherein, the memory stores an instruction program that can be executed by at least one processor, and the instruction program is executed by at least one processor, so that at least A processor can execute the above-mentioned method for robot voice command recognition.

[0062] The processor 310 and the memory 320 may be connected via a bus or other means, image 3 Take connection via bus as an example.

[0063] The memory 320, as a non-volatile computer-readable storage medium, can be used to store non-volatile software programs, non-volatile computer-executable programs and modules, such as the method corresponding to the robot v...

Abstract

A voice instruction recognition method for a robot, and a related robot device. The method comprises: when it is detected that a user starts speaking and the current voice instruction recognition accuracy is less than a pre-set accuracy threshold value, adjusting an operating state of a robot until the adjusted voice instruction recognition accuracy of the robot reaches the pre-set accuracy threshold value. The method can enable a robot device to receive a voice instruction more accurately without stopping operation, and better coordinates the voice instruction recognition accuracy and operating efficiency.

Description

technical field [0001] The embodiments of the present invention relate to the field of robots, in particular to a method for recognizing voice commands of a robot and a related robot device. Background technique [0002] When the current movable and mechanically capable robot is working, due to the operation of the steering gear and / or motor, or the operation or cleaning of other objects (such as door opening operation, dishwashing operation, sweeping operation, etc.), it is inevitable Noise is generated, and if the user issues voice commands to the robot during this process, the noise will inevitably have a certain impact on the accuracy of the robot's speech recognition. Even if there is a noise reduction algorithm, it can only filter the steady-state noise, and it is difficult to filter out the changing and unpredictable noise during the robot's working process. Another method is that the robot stops the current action after detecting the user's voice, and continues the ...
