End-to-end virtual object animation generation method and apparatus, storage medium, and terminal

A non-transitory storage medium, storing a computer program which, when executed by a processor, causes the processor to perform the following steps:

• receiving input information, wherein the input information comprises text information or audio information of a virtual object animation to be generated;
• converting the input information into a pronunciation unit sequence;
• performing a feature analysis of the pronunciation unit sequence to obtain a corresponding linguistic feature sequence;
• and
• inputting the linguistic feature sequence into a preset timing mapping model to generate the virtual object animation based on the linguistic feature sequence;
• wherein performing the feature analysis of the pronunciation unit sequence to obtain the corresponding linguistic feature sequence comprises:
• performing a feature analysis of each pronunciation unit in the pronunciation unit sequence to obtain a linguistic feature of the each pronunciation unit;
• and
• generating the corresponding linguistic feature sequence based on the linguistic feature of the each pronunciation unit;
• and
• wherein performing the feature analysis of the each pronunciation unit in the pronunciation unit sequence to obtain the linguistic feature of the each pronunciation unit comprises:
• analyzing a pronunciation feature of the each pronunciation unit to obtain an independent linguistic feature of the each pronunciation unit;
• analyzing a pronunciation feature of an adjacent pronunciation unit of the each pronunciation unit to obtain an adjacent linguistic feature of the each pronunciation unit;
• and
• generating the linguistic feature based on the independent linguistic feature and the adjacent linguistic feature.

A terminal, comprising a memory and a processor, wherein the memory stores a computer program executable by the processor, and the processor is configured to perform the following steps:

• receiving input information, wherein the input information comprises text information or audio information of a virtual object animation to be generated;
• converting the input information into a pronunciation unit sequence;
• performing a feature analysis of the pronunciation unit sequence to obtain a corresponding linguistic feature sequence;
• and
• inputting the linguistic feature sequence into a preset timing mapping model to generate the virtual object animation based on the linguistic feature sequence;
• wherein performing the feature analysis of the pronunciation unit sequence to obtain the corresponding linguistic feature sequence comprises:
• performing a feature analysis of each pronunciation unit in the pronunciation unit sequence to obtain a linguistic feature of the each pronunciation unit;
• and
• generating the corresponding linguistic feature sequence based on the linguistic feature of the each pronunciation unit;
• and
• wherein performing the feature analysis of the each pronunciation unit in the pronunciation unit sequence to obtain the linguistic feature of the each pronunciation unit comprises:
• analyzing a pronunciation feature of the each pronunciation unit to obtain an independent linguistic feature of the each pronunciation unit;
• analyzing a pronunciation feature of an adjacent pronunciation unit of the each pronunciation unit to obtain an adjacent linguistic feature of the each pronunciation unit;
• and
• generating the linguistic feature based on the independent linguistic feature and the adjacent linguistic feature.
