Mouth shape animation generation method and apparatus, device, and medium

A mouth shape animation generation apparatus, comprising:

• a generation module, configured to perform feature analysis based on a target audio to generate viseme feature flow data, the viseme feature flow data comprising a plurality of sets of ordered viseme feature data, each set of viseme feature data corresponding to one audio frame in the target audio;
• a parsing module, configured to separately parse each set of viseme feature data to obtain viseme information and intensity information corresponding to the respective set of viseme feature data, the intensity information being used for characterizing a change intensity of a viseme corresponding to the viseme information;
• and
• a control module, configured to control, according to the viseme information and the intensity information corresponding to the sets of viseme feature data, a virtual face to change, so as to generate a mouth shape animation corresponding to the target audio.

A computer device comprising:

• a memory;
• and
• one or more processors,
• wherein the memory stores computer-readable instructions, and the processor, when executing the computer-readable instructions, causes the computer device to perform:
• feature analysis based on a target audio, to generate viseme feature flow data, the viseme feature flow data comprising a plurality of sets of ordered viseme feature data, each set of viseme feature data corresponding to one audio frame in the target audio, respectively;
• separate parsing of each set of viseme feature data, to obtain viseme information and intensity information corresponding to the respective set of viseme feature data, the intensity characterizing a change intensity of a viseme corresponding to the viseme information;
• and
• controlling, according to the viseme information and the intensity information corresponding to the sets of viseme feature data, a virtual face to change, so as to generate a mouth shape animation corresponding to the target audio.

One or more computer-readable storage media, storing computer-readable instructions, the computer-readable instructions, when executed by one or more processors, causes a computing apparatus to:

• perform feature analysis based on a target audio, to generate viseme feature flow data, the viseme feature flow data comprising a plurality of sets of ordered viseme feature data, each set of viseme feature data corresponding to one audio frame in the target audio, respectively;
• separately parse each set of viseme feature data, to obtain viseme information and intensity information corresponding to the respective set of viseme feature data, the intensity characterizing a change intensity of a viseme corresponding to the viseme information;
• and
• control, according to the viseme information and the intensity information corresponding to the sets of viseme feature data, a virtual face to change, so as to generate a mouth shape animation corresponding to the target audio.
