"Animation lip sync" PlugIT
The "Animation lip sync" PlugIT allows to animate the lips of a virtual character (and the tongue) depending on the phonetic of the speech. It is based on the concept of "viseme" ("visual phoneme"), the concept use the position of the lips/tongue/Jaw while a phoneme pronunciation, a same viseme can be used for severals phonemes (for example, "B" and "P" have the same lip movements in english).
Parameters |
|
1 |
Necessary time for a viseme animation to switch to a weight "0" to a weight "1". If the character speak quickly, it can be necessary to lower this parameter (and to increase it in the opposite case). |
2 |
Viseme/animation panel. Select here the pose type animation of the character lip position for a specific viseme. |
Action |
|
Inject viseme |
Injects a viseme animation sets in the link parameter. The using visemes are from "Mr.Preston Blair" works, namely the values : "rest", "AI", "E", "etc", "FV", "L", "MBP", "O", "U", ou "WQ" . The set of viseme by default are compatible with the viseme informations outputed by the "Speech" PlugIT. |
Complementary information about the visemes.
For ease of reference, we only use 10 animations instead of 21 in english) (including the "silence" pose). Thus, we use the same viseme when they are relatively close (for example "S-Z" et "TH-DH" in english).
The next panel illustrates the lip poses of theses 10 animations.
