Embodiment 1

[0025] figure 1 It shows a schematic diagram of the implementation flow of a robot-based voice information receiving method provided in Embodiment 1 of the present application, and is described in detail as follows:

[0026] Step S11, when a user appears within the preset range, acquire the orientation relationship between the user and the robot;

[0027] In the embodiment provided by this application, when the robot is preparing to receive the voice information sent by the user, it initializes the visual recognition engine and the voice engine of the robot, and then monitors whether there is a user within the preset range. When a user appears within the preset range , acquire the orientation of the user, and determine the orientation relationship between the robot and the user.

[0028] Wherein, the user includes a controller of the robot, and the user may be a human being or a smart device controlling the robot. The orientation relationship includes the position or directi...

Embodiment 2

[0042] figure 2 It shows a schematic diagram of the implementation flow of a robot-based voice information receiving method provided by another embodiment of the present application, and is described in detail as follows:

[0043] Step S21, when a user appears within the preset range, obtain the identity authentication information of the user;

[0044] judging whether the user is a preset user according to the identity authentication information;

[0045] When the user is a preset user, acquire an orientation relationship between the user and the robot.

[0046]In the embodiment provided by this application, when the robot detects that a user appears within the preset range, the identity of the user that appears is verified. At this time, the user's identity authentication information is obtained, and the identity authentication information includes the user's photo, for example Determine whether the user is a preset user by taking a photo of the user, and then acquire the ...

Abstract

The invention is suitable for the technical field of robots, and provides a voice information receiving method and system based on a robot, and terminal equipment, and the method comprises the steps:obtaining the azimuth relation between a user and the robot when the user appears in a preset range; instructing a microphone array to acquire voice information sent by the user according to the orientation relationship; and identifying the voice information, and executing an action corresponding to the voice information. In the process, even if the robot does not receive the awakening word sent by the user, the direction of receiving the voice information by the microphone array is determined according to the acquired orientation relationship between the robot and the user, so that the microphone is indicated to receive the voice information in the direction of the sound emitted by the user, the reception of the sound transmitted from other directions is reduced, the hearing of the robotis more sensitive and accurate, the robot is more intelligent, and the user experience is better.

Description

technical field [0001] The present application belongs to the technical field of robots, and in particular relates to a robot-based voice information receiving method, system and terminal equipment. Background technique [0002] Speech recognition is the process of converting human voice signals into words or instructions. Speech recognition takes speech as the research object, and it is an important research direction of speech signal processing. With the continuous development of science and technology, all kinds of robots continue to enter people's lives and facilitate people's lives in different ways. When the robot recognizes the user's voice, in order to improve the accuracy of the robot's recognition of the user's voice, it is generally necessary to enable the microphone array to receive voice in a directional manner. This process requires the user to issue a wake-up word first to allow the robot to determine the user's location. However, the user often forgets to i...
