However, a burgeoning record of research findings reveals that our perception and understanding are influenced by a speaker's face and accompanying gestures, as well as the actual sound of the speech. Perceivers expertly use these multiple sources of information to identify and interpret the language input. Given the value of face-to-face interaction, our persistent goal has been to develop, evaluate, and apply animated agents to produce realistic and accurate speech. Baldi ® is an accurate threedimensional animated talking head appropriately aligned with either synthesized or natural speech. Baldi has a realistic tongue and palate, which can be shown by making his skin transparent. Based on this research and technology, we have implemented | |||||||||||||||
