Abstract: Embodiments of the present disclosure relate to a method and apparatus for controlling mouth shape changes of a three-dimensional virtual portrait, relating to the field of cloud computing. The method may include: acquiring a to-be-played speech; sliding a preset time window at a preset step length in the to-be-played speech to obtain at least one speech segment; generating, based on the at least one speech segment, a mouth shape control parameter sequence for the to-be-played speech; and controlling, in response to playing the to-be-played speech, a preset mouth shape of the three-dimensional virtual portrait to change based on the mouth shape control parameter sequence.

Abstract: Embodiments of the present disclosure provide a method and apparatus for generating information, and relate to the field of cloud computation. The method may include: receiving a video and an audio of a user from a client; analyzing the video and the audio to determine an intention category of the user; generating feedback information according to the intention category of the user and a preset service information set; generating a video of a pre-established three-dimensional virtual portrait by means of an animation engine based on the feedback information; and transmitting the video of the three-dimensional virtual portrait to the client, for the client to present to the user.
