Abstract: A digital voice assistant operation system includes an access point, an electronic device, an audio device and a digital voice assistant module. The access point is in communication with a voice recognition module through network connection. The electronic device is in communication with the access point through network connection. After the user provides a voice command to the audio device, the voice command is transmitted to the voice recognition module through the audio device, the digital voice assistant module and the access point. After the voice recognition module recognizes the voice command, an operating signal corresponding to the voice command is outputted from the voice recognition module to the electronic device. Consequently, the electronic device performs an operation according to the operating signal.

Abstract: A Bluetooth pairing system includes an external device and a host device. The external device includes a Bluetooth module, a first transmission interface and a USB controller. When the external device is connected with the host device, a standard handshaking message complying with a USB communication protocol is issued from the processor to the external device. After the standard handshaking message is received by the USB controller of the external device, a device descriptor of the external device is transmitted from the USB controller to the host device. The device descriptor contains a vendor identification code, a product identification code, a product string and a product type of the external device and a target communication address of the Bluetooth module. The host device analyzes the device descriptor to acquire the target communication address of the Bluetooth module.
