Problems solved by technology

[0005] However, in the above voice wake-up process, it takes a long time to restore power to the second system, generally about 200ms to 1000ms
It can be seen that although the dual system can reduce the power consumption of the electronic device, when the voice assistant application is launched, it will involve restoring the power to the second system in the power-off state, and the power required for the second system to restore the power Time will increase the delay of the voice wake-up function of electronic devices, resulting in excessive wake-up delay

Embodiment 1

[0175] The preset power-on condition is: the sound information includes human voice, and the electronic device maintains the preset posture for a time greater than a time threshold. The following combination Figure 9 An embodiment corresponding to the preset power-on condition will be described.

[0176] Figure 9 It is a schematic flowchart of a voice wake-up method provided in the embodiment of the present application. see Figure 9 , the method can include:

[0177] Step 201, please refer to step 101, which will not be repeated here.

[0178] Step 202, if the first system receives the voice information, perform voice activity detection on the voice information.

[0179] Wherein, the first system may perform voice activity detection on the voice information through the voice activity detection unit. For example, the electronic device collects sound information through a digital microphone and sends it to a voice activity detection unit, and the voice activity detectio...

Embodiment 2

[0201] The preset power-on condition is: the sound information contains human voice, and the user's body is close to the electronic device. The following combination Figure 10 An embodiment corresponding to the preset power-on condition will be described.

[0202] Figure 10 It is a schematic flowchart of another voice wake-up method provided in the embodiment of the present application. see Figure 10 , the method can include:

[0203] For steps 301-302, refer to steps 201-202, which will not be repeated here.

[0204] Step 303: If the sound information includes human voice, the first system activates the voice signal processing unit of the first system, and detects whether the user's body is close to the electronic device.

[0205] Based on the relevant content in step 203, if the voice information includes human voice, it means that the user may wake up the electronic device through a voice command. Further, the fact that the user's body is close to the electronic de...

Embodiment 3

[0215] The preset power-on condition is: the sound information contains human voice, and the user looks at the screen of the electronic device. The following combination Figure 11 An embodiment corresponding to the preset power-on condition will be described.

[0216] Figure 11 It is a schematic flowchart of another voice wake-up method provided in the embodiment of the present application. see Figure 11 , the method includes:

[0217] Steps 401-402, refer to steps 201-202, which will not be repeated here.

[0218] Step 403, if the sound information includes human voice, the first system activates the voice signal processing unit of the first system, and detects whether the user looks at the screen of the electronic device.

[0219] Based on the relevant content in step 203, if the voice information includes human voice, it means that the user may wake up the electronic device through a voice command. Further, after the screen is turned on, the user looks at the scree...

Abstract

The invention is suitable for the technical field of terminals, and provides a voice wake-up method, electronic equipment and a chip system. The electronic equipment comprises a first system, a second system and a power management unit, and when the electronic equipment is in a screen-off state, the first system is in a power-on state, and the second system is in a power-off state; the first system is used for lightening a screen of the electronic equipment; the first system is also used for detecting a preset power-on condition under the condition that the sound information is received, and performing first voice recognition on the sound information; the first system is further used for powering on the second system through the power management unit under the condition that the preset powering-on condition is detected; and the second system is used for starting the target application when the power-on is completed and the first voice recognition result meets the first preset condition. The electronic equipment can shorten or eliminate the time delay generated by electrifying the second system, so that the voice wake-up time delay can be greatly reduced, the target application is quickly started, and the waiting time of a user is shortened.

Description

technical field [0001] The present application relates to the field of terminal technology, and in particular to a voice wake-up method, electronic equipment and a chip system. Background technique [0002] As a typical application of artificial intelligence, the application of voice assistant is becoming more and more popular in electronic equipment. Voice wake-up is the entrance of voice assistant applications, and its performance indicators and wake-up delay greatly affect the user experience. Voice wake-up means that a wake-up word is preset in the electronic device. When the user issues a voice command containing the wake-up word, the voice assistant application will wake up from the dormant state and respond, thereby greatly improving the efficiency of human-computer interaction. [0003] At present, for electronic devices with high power consumption requirements, dual systems can be used to increase the battery life of the electronic devices. For different scenarios...
