Claim 5:
6. 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 the Chinese pinyins in the Chinese pinyin sequence according to a timing sequence of the reference audio, to obtain time stamps of the Chinese pinyins;
searching in a pinyin-grid dictionary to obtain a three-dimensional face grid sequence corresponding to the each of the Chinese pinyins, the pinyin-grid dictionary being used to represent a corresponding relationship between a Chinese pinyin and a three-dimensional face grid sequence;
stitching, based on the time stamps, three-dimensional face grid sequences corresponding to the Chinese pinyins in the Chinese pinyin sequence, to obtain a three-dimensional face grid sequence corresponding to the timing sequence of the reference audio;
obtaining the animation of facial expressions based on the three-dimensional face grid sequence corresponding to the timing sequence of the reference audio.
