Embodiment 1

[0055] see figure 1 , the user identity recognition method of voice command in the vehicle of the present invention specifically comprises:

[0056] Step 101, receiving a voice instruction from the user;

[0057] Step 102, determining the number of users in the vehicle and the user identity of each user, where the user identity of each user is one of the preset user identities;

[0058] Step 103, when the number of users is 1, use the user identity of the user as the user identity of the voice command, and when the number of users is greater than 1, identify the user of the voice command based on microphone array beamforming identity.

[0059] The user identification method for voice commands in a vehicle in Embodiment 1 of the present invention will be described in detail below.

[0060] In step 101, the voice command is a voice command that includes a wake-up word. For example, the voice command can be "Hello, Xiao Mo". In another embodiment, the above-mentioned voice com...

Embodiment 2

[0076] see figure 2 , the user identity recognition method of voice command in the vehicle of the present invention specifically comprises:

[0077] Step 101, initialize the voice command identity field;

[0078] Step 102, determining the number of users in the vehicle and the user identity of each user; the user identity of each user is one of the preset user identities;

[0079] Step 103, when the number of users is 1, the value of the voice command identity field is set as the user identity of the user;

[0080] Step 104, receiving a voice instruction from the user;

[0081] Step 105, judging whether the value of the voice command identity field belongs to the preset user identity, if so, using the value of the voice command identity field as the user identity of the voice command, otherwise, based on the microphone Array beamforming to identify the user identity of the voice command.

[0082] The user identity recognition method of the voice command in the vehicle of th...

Abstract

The embodiment of the present invention discloses a method and device for identifying user identity of a voice command in a vehicle. The method includes: step 101, receiving a voice command sent by a user; step 102, determining the number of users in the vehicle and the user identity of each user , the user identity of each user is one of the preset user identities; Step 103, when the number of users is 1, the user identity of the user is used as the user identity of the voice command, when the user identity is When the number of users is greater than 1, the user identity of the voice instruction is identified based on the microphone array beamforming. Through the above method, the processing load of the vehicle machine can be reduced, the speed of user identification of the voice command can be improved, and the user's command can be responded more quickly.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method and device for identifying user identity of voice commands in vehicles. Background technique [0002] With the rapid development of Internet information technology, automotive electronics, and voice control technology, more and more car manufacturers have begun to install intelligent voice control systems in the car. Users can control the car to perform specific operations through voice, such as turning on or off. Air conditioners, car windows, sunroofs, setting / modifying navigation, turning on music playback, etc., greatly enhance the user experience through voice and car-machine interaction. [0003] With the control of the intelligent voice control system, the need to recognize the identity of the user of the voice command has gradually emerged. [0004] On the one hand, if other people in the vehicle other than the driver...
