Classification: CPC G | IPC G

Claim 0:
1. A method for generating animation, comprising:
processing to-be-processed material to generate a normalized text;
analyzing the normalized text to generate a Chinese pinyin sequence of the normalized text;
generating a reference audio based on the to-be-processed material;
aligning the reference audio and respective Chinese pinyins in the Chinese pinyin sequence according to a timing sequence of the reference audio, to obtain time stamps of the respective Chinese pinyins;
searching in a pinyin-expression coefficient dictionary to obtain an expression coefficient sequence corresponding to each of the Chinese pinyins, the pinyin-expression coefficient dictionary being used to represent a corresponding relationship between a Chinese pinyin and an expression coefficient sequence;
stitching, based on the time stamps, expression coefficient sequences corresponding to the Chinese pinyins in the Chinese pinyin sequence, to obtain an expression coefficient sequence corresponding to the timing sequence of the reference audio; and
obtaining animation of facial expressions corresponding to the timing sequence of the reference audio based on the expression coefficient sequence corresponding to the timing sequence of the reference audio.
