Embodiment 1

[0052] figure 1 It is a schematic flowchart of a voice interaction control method for a smart device according to an embodiment of the present invention, see figure 1 , the voice interaction control method includes:

[0053] Step S11, monitor and collect the voice signal sent by the user of the smart device in real time;

[0054] Step S12, performing speech recognition on the collected speech signal;

[0055] Step S13, according to the voice recognition result of the smart device on the voice signal, wake up the corresponding function of the smart device and determine whether to control the smart device to move, if yes, obtain the user's position, control the smart device to move toward the user, and shorten the distance between the smart device and the user. The distance is to recognize the voice signal sent by the user again; otherwise, directly control the smart device to perform the corresponding operation according to the voice recognition result.

Embodiment 2

[0059] figure 2 It is a schematic flowchart of a voice interaction control method for a smart device according to an embodiment of the present invention. The following combination figure 2 The implementation steps and principles of the voice interaction control method according to the embodiment of the present invention are described in detail. see figure 2 , the method of this embodiment includes the following steps S21 to S27.

[0060] process starts;

[0061] In step S21, it is judged whether there is a user's voice input; if yes, step S22 is performed, otherwise, the process can be ended.

[0062] Step S22, executing the wake-up algorithm and sound source localization;

[0063] After collecting the voice signal from the user, the voice signal processing function inside the intelligent robot executes the wake-up algorithm and sound source localization according to the voice signal.

Embodiment 3

[0099] In this embodiment, a specific application scenario of the voice interaction control method of the smart device according to the embodiment of the present invention is listed.

[0100] In this embodiment, the smart device is specifically a service robot, and the server robot can execute the voice interaction control method of the smart device according to the embodiment of the present invention.

[0101] The robot and 3-year-old Xiao Ming are both in the living room. Xiao Ming wakes up the robot by voice. If the robot is not awakened, it does not respond.

[0102] The initial distance between Xiao Ming and the robot is within 2 meters. Xiao Ming said to the robot: "Harry, I want to hear the story." If he didn't hear it clearly, the robot asked: "I didn't hear it clearly, please say it again."

[0103] At the same time, the robot calculates the sound from which direction according to the sound signal sent by Xiao Ming, the face turns to this direction to respond, and mov...

Abstract

The invention discloses a voice interaction control method and device for intelligent equipment, and the method comprises the steps: monitoring and collecting a voice signal, sent by an intelligent equipment user, in real time; carrying out the voice recognition of the collected voice signal; wakening the corresponding functions of the intelligent equipment according to the voice recognition result of the voice signal, and determining whether to control the intelligent equipment to move or not: obtaining the position of the user if the intelligent equipment is controlled to move, controlling the intelligent equipment to move towards the user, shortening the distance between the intelligent equipment and the user, and recognizing another voice signal sent by the user; or else, controlling the intelligent equipment to carry out the corresponding operation according to the voice recognition result. According to the technical scheme of embodiment of the invention, the method controls the intelligent equipment to move towards the user according to the voice recognition result when a voice instruction of the user cannot be heard clearly because of long distance, thereby achieving the near-field voice interaction, ironing out the defect that a far-field voice recognition effect is poor, and providing natural and smooth interaction experience for the user.

Description

technical field [0001] The present invention relates to the technical field of voice interaction of intelligent equipment, in particular to a method and device for voice interaction control of intelligent equipment. Background technique [0002] At present, consumer smart devices usually have a voice interaction function, which can recognize and understand the user's voice commands and conduct voice dialogues. Existing smart devices usually need to wake up by voice before performing voice interaction. [0003] The process of voice wake-up is mainly as follows: the user first needs to say a wake-up word, and the wake-up word may be preset for a specific smart device. The smart device detects the voice, extracts the voice features, and determines whether the extracted voice features match the voice features of the preset wake-up words. If they match, the wake-up recognition function performs voice recognition and semantic analysis on the subsequent voice commands issued by th...
