A network control method relates to the communications field, includes receiving, by a controller, a packet forwarded by a forwarder, detecting, by the controller, a status of a virtual currency identifier of the packet, querying, by the controller according to a user identifier in the packet, whether the user has permission to improve service quality when the status of the virtual currency identifier of the packet indicates that a user is willing to pay virtual currency to raise a network priority, and raising, by the controller, the network priority of the user, starting charging, and sending a network priority of the user to the forwarder when the user has the permission to improve the service quality such that the forwarder forwards a packet of the user according to the network priority of the user.

A method and device for speaker recognition are provided. In the present invention, identifiability re-estimation is performed on a first vector (namely, a weight vector) in a score function by adopting a support vector machine (SVM), so that a recognition result of a characteristic parameter of a test voice is more accurate, thereby improving identifiability of speaker recognition.

Method and device for speaker recognition

An encoding method includes: extracting core layer characteristic parameters and enhancement layer characteristic parameters of a background noise signal, encoding the core layer characteristic parameters and enhancement layer characteristic parameters to obtain a core layer codestream and an enhancement layer codestream. The disclosure also provides an encoding device, a decoding device and method, an encapsulating method, a reconstructing method, an encoding-decoding system and an encoding-decoding method. By describing the background noise signal with the enhancement layer characteristic parameters, the background noise signal can be processed by using more accurate encoding and decoding method, so as to improve the quality of encoding and decoding the background noise signal.
