Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides a robot and its voice interaction system to solve the problem that many robots now adopt the working mode of continuous listening. This working mode makes it easy for the robot to misrecognize the voice when the environmental noise is relatively large. , which leads to the problem that when no one talks to the robot, the robot will also speak by itself, and the user experience is poor

Embodiment 1

[0038] Such as figure 1 As shown, this embodiment provides a robot voice interaction system 10, which includes a face detection module 1, a lip movement detection module 2, and a voice pickup extraction module 3 connected in sequence.

[0039] In specific applications, the robot may be any type of robot that includes the voice interaction system and has voice interaction functions, such as service robots, underwater robots, entertainment robots, military robots, agricultural robots, roboticized machines, and so on.

[0040] It should be understood that, in actual applications, depending on the specific purpose and application of the robot, the robot may also include power supply devices, mechanical motion mechanisms, wireless network communication modules and other components. In the various embodiments of the present invention and corresponding drawings, Only the parts closely related to the present invention are shown exemplarily, and do not constitute a limitation on the specific...

Embodiment 2

[0049] Such as figure 2 As shown, in this embodiment, the face detection module 1 is also used to send a notification that no face is detected to the voice pickup extraction module 3 when no face is detected, and continue to detect the face;

[0050] The voice pickup and extraction module 3 is also used to enter the dormant state when receiving a notification that a human face is not detected or when a notification that a human face is detected is not received.

[0051] In specific applications, by sending a notification that no face is detected to the voice pickup and extraction module when no face is detected, the voice pickup and pickup module will not receive the detection when it receives the notification that no face is detected or not. When the face is notified, it enters the dormant state, which can prevent the voice pickup and extraction module from being in a state (working state) listening to sounds in the current environment for a long time, so as to reduce power consum...

Embodiment 3

[0088] Such as Figure 5 As shown, in this embodiment, the voice interaction system 10 in Embodiment 1 or Embodiment 2 further includes:

[0089] The natural semantic analysis module 4 connected to the voice pickup extraction module 3 is used to perform natural semantic analysis on the voice signal and recognize the meaning of the voice signal; and

[0090] The voice playback module 5 connected to the natural voice analysis module 4 is used to search for and play corresponding voice data according to the meaning of the voice signal.

[0091] In specific applications, the voice pickup extraction module, natural voice analysis module, and voice playback module can be wired through physical connections such as serial data bus, cable, optical fiber, etc., or through Bluetooth module, WiFi module, ZigBee module, etc. The wireless communication module realizes a wireless connection. The natural voice analysis module and the voice playback module can be sub-function partition modules of en...

Abstract

The invention is applicable to the technical field of robots, and provides a robot and a voice interaction system thereof. The voice interaction system comprises a human face detection module, a lip movement detection module and a voice pickup extraction module which are connected in sequence; the human face detection module is used for detecting a human face and sending a notification that the human face is detected to the lip movement detection module when the human face is detected; the lip movement detection module is used for detecting lip movement when receiving the notification that thehuman face is detected, and sending the notification that the lip movement is detected to the voice pickup extraction module when detecting the lip movement; and the voice pickup extraction module isused for entering a working state when receiving the notification that the lip movement is detected, and carrying out pickup on the current environment so as to extract a voice signal in the currentenvironment. The robot and the voice interaction system thereof can ensure that the voice signal in the current environment starts to be extracted only when a person speaks, wrong recognition can be avoided, the user experience is improved, and the power consumption can be effectively reduced.

Description

Technical field [0001] The invention belongs to the technical field of robots, and particularly relates to a robot and a voice interaction system thereof. Background technique [0002] With the continuous development of robotics technology, various intelligent robots emerge in an endless stream, and are widely used in various fields such as finance, home furnishing, manufacturing, construction, and medical care, bringing great convenience to people's daily production and life. At present, robots with intelligent voice interaction function are popular because of their practicality and fun. [0003] However, in order to make the robot's voice communication more natural, smooth and intelligent, many robots now adopt a continuous listening working mode. This working mode makes it easy for the robot to misrecognize the voice when the environment is noisy. When talking to a robot, the robot will also speak on its own, and the user experience is poor. Summary of the invention [0004] In...
