Abstract:
Embodiments of this application provide a voice interaction method. In the interaction method an electronic device receives a first voice signal, where the first voice signal includes a wake-up word. The electronic device switches from a standby state to a working state based on the wake-up word, and the electronic device outputs a second voice signal in a first tone, where the second voice signal is used to respond to the first voice signal. The first tone is obtained based on personal information associated with a voiceprint feature of the first voice signal, and the personal information includes personal information corresponding to a first registered voice signal. In a plurality of registered voice signals, a voiceprint feature of the first registered voice signal is most similar to the voiceprint feature of the first voice signal.
Abstract:
Embodiments of the present invention provide an antenna apparatus. The antenna apparatus includes multiple antennas, a switching unit, a grounding layer, connecting lines and a dielectric substrate. The antennas are configured to transmit and receive electromagnetic waves. The connecting lines are configured to connect the switching unit and the antennas. The switching unit is configured to selectively feed signals to the antennas through the connecting lines. The grounding layer serves as a reference of zero potential, and by setting the shape or size of the grounding layer and the distance from the grounding layer to the antennas, the grounding layer is further configured to restrain a transmitting direction of the electromagnetic waves transmitted by the antennas. The dielectric substrate is configured to allow the grounding layer to be printed thereon, and the dielectric substrate is further configured to allow the antennas, the switching unit and the connecting lines.
