AI Technical Summary

Problems solved by technology

In addition, the lack of consideration of background noise and background images in the prior art makes the animation not vivid and realistic enough, and it is impossible to simulate the scene according to the actual needs, and adjust the noise according to the needs to improve the effect of the animation

Embodiment Construction

[0028] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0029] An Analysis of the Characters of the Pronunciation and Mouth Shapes of Chinese Pinyin

[0030] The basic units of speech are divided into phoneme, syllable, tone and phoneme from the perspective of timbre. A phoneme is the smallest unit or the smallest sound segment that constitutes a syllable. If a syllable is further divided according to the different timbres, the smallest unit with its own characteristics will be obtained, which is the phoneme. There are 32 phonemes in Mandarin speech, which can be divided into two categories: vowels and consonants. The...

Abstract

The invention discloses a mouth shape animation synthesis method based on a comprehensive weighted algorithm. The mouth shape animation synthesis method comprises the following steps: analyzing input Chinese texts, splitting Chinese characters into different Chinese visual phonemes, sending the phonemes to a voice synthesis system, synthesizing the phonemes to form a basic visual phoneme flow, establishing a parameter human face model with reality sense based on an MPEG-4 standard, driving the deformation of the model by using visual phoneme animation frame parameters, adding background images, and performing hierarchical processing and addition on noises, so that the mouth shape animation synthesis with vividness, reality and good effect can be achieved.

Description

technical field [0001] The invention relates to the research field of facial expression animation, more specifically to the research field of lip animation synthesis of mouth shape and voice matching. Background technique [0002] With the continuous advancement of computer animation technology, people have higher and higher requirements for lip animation in human-computer interaction. However, the development of Chinese lip animation is relatively backward. On the one hand, because lip animation is a multidisciplinary research direction, including human-computer interaction, computer graphics, speech linguistics, etc., and the development of related disciplines is uneven, it makes the construction of a realistic and highly automated lip animation The system is still a very challenging research topic. On the other hand, 1 / 4 of the people in the world speak Chinese, and the Chinese lip-animation system has an extremely broad application market. Relatively few, the developm...
