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.
