Example 1

The voice wake-up device shown in FIG. 1 includes an infrared detection device 1, a control device 2, a voice module 3, and an information matching module 4.

The infrared detection device is used to detect the distance between the user and the electronic device; the control device is used to determine whether the distance between the user and the electronic device is within a set range, and the voice module is started or hibernated according to the judgment result; and determined according to the matching result of the information matching module A control instruction having a corresponding relationship with the instruction information, and the electronic device is controlled according to the control instruction.

The voice module is used to collect voice information and give voice prompts when starting or sleeping.

It also includes an LED light 5 for prompting when the voice module starts or sleeps.

The voice wake-up device is configured with an infrared sensor, which can detect whether a person is close to a preset distance (such as 30 cm) of the voice device.

In the first method, when the user is not using a voice device, the voice device handles the standby state, and its voice module does not wake up. At this time, the infrared sensor periodically (for example, 300ms) detects whether someone is approaching, and once it is detected, for example, 30cm Within, it will trigger a voice wake-up, and give a voice prompt or change the display or remind the user by blinking the LED light, etc. At this time, the user can directly speak the voice command word to control the device.
