Communication, Co-articulation and Dialog Gesture in Facial Animation

9117110 Badler这是一项为期三年的持续资助的第三年。本研究的目标是面部表情的三维动画，包括那些与语音语调相关的情感表达。这包括时间、音高和重音的区分，这些都与话语作为“给定”和“新”信息的语义区分有关。到目前为止，现有的系统还没有考虑到这两个特征之间的联系。要使用的算法将包含控制这些不同表达模式的规则。重音的选择及其位置将与消息是新的还是旧的结合起来进行检查。面部模型整合了每个肌肉或肌肉群的动作以及它们运动的传播。我们还将研究一个两人对话模型，以探索听者和说话者的角色，以及轮流是如何通过面部和手势建立起来的。

9117110 Badler This is the third year of a three-year continuing grant. The goal of this research is 3-D animation of facial expressions including those conveying emotion correlated with the intonation of the voice. This includes differentiation of timing, pitch and emphasis that are related to semantic distinctions of discourse as "given" and "new" information. Until now, existing systems have not taken into account the link between these two features. The alogrithm to be used will embody rules that control these various modes of expression. The choice of accents and their placement will be examined in conjunction with whether the message is new or old. The facial model integrates the action of each muscle or group of muscles as well as the propagation of their movement. A two-person conversation model will also be investigated to explore the roles of the listener and the speaker and how turn-taking is established facially and by gestures.
