    Abstract: This application provides a multicast service providing method and a software defined networking (SDN) controller. The method implemented by the SDN controller includes the operations of: obtaining target path establishment information; obtaining a target multicast IP address corresponding to target service data and a target multicast MAC address corresponding to the target service data; and separately sending a target forwarding rule to a plurality of forwarding devices on the target path. Based on the foregoing technical solution, a service server may send, to a terminal device through unicast, target service data requested by the terminal device. The terminal device may further receive, through unicast, the target service data sent by the service server. In this way, neither the service server nor the terminal device needs to support a multicast protocol.

    Abstract: A statistical parameter modeling method is performed by a server. After obtaining model training data, the model training data including a text feature sequence and a corresponding original speech sample sequence, the server inputs an original vector matrix formed by matching a text feature sample point in the text feature sample sequence with a speech sample point in the original speech sample sequence into a statistical parameter model for training and then performs non-linear mapping calculation on the original vector matrix in a hidden layer, to output a corresponding prediction speech sample point. The server then obtains a model parameter of the statistical parameter model according to the prediction speech sample point and a corresponding original speech sample point by using a smallest difference principle, to obtain a corresponding target statistical parameter model.
