Abstract: This application relates to a cross-network-segment discovery method and system, and a routing device. The method includes: An electronic device A sends, to an electronic device B, a DLNA delivery message that includes a URL and an identifier of the electronic device B. The electronic device B plays content corresponding to the URL. After the electronic device A moves from an area A to an area B, the electronic device A disconnects from a routing device A, and connects to a routing device B. The electronic device A sends, to the routing device B, a first request message that includes a fixed multicast address. The routing device B forwards the first request message to the routing device A. The routing device A sends the first request message in a multicast mode within a range of a first multicast address. The electronic device B sends a first response message to the electronic device A by using the routing device A and the routing device B. The electronic device A discovers the electronic device B. In this way, cross-network-segment automatic discovery may be implemented, to provide convenience for a user and improve user experience.

Abstract: This application provides a voiceprint recognition method and device. The method includes: calculating, by an electronic device a first confidence value that an entered voice belongs to a first registered user, and calculating a second confidence value that the entered voice belongs to a second registered user. The method further includes: calculating, by another electronic device, a third confidence value that the entered voice belongs to the first registered user, and calculating a fourth confidence value that the entered voice belongs to the second registered user. A server determines, based on the first confidence value and the third confidence value, a fifth confidence value that a user is the first registered user, and determines, based on the second confidence value and the fourth confidence value, a sixth confidence value that the user is the second registered user.
