本研究旨在探讨教学代理人的形象与声音对学生认知与学习的影响。教学代理具有不同的形象（专家型vs导师型）和声音（强势型vs冷静型vs计算机生成型），但具有相同的手势、情感、评论和性别。109名计算机扫盲课程的本科生被随机分配到六种情况中的一种。结果显示，代理人形象对角色感知有显著的主要影响：正如假设的那样，导师形象被认为更具激励性。此外，声音也有显著的主要影响：强有力的声音总体上是最具激励作用的，而人类的声音（强有力的或平静的）都被认为比计算机生成的声音更亲切、更有情感、更可信、更有利于学习。代理人的形象和声音对其无显著影响
The purpose of this study was to examine the effects of image and voice of pedagogical agents on student perception and learning. Pedagogical agents were developed with differing image (expert-like vs. mentor-like) and voice (strong vs. calm vs. computer-generated), but with identical gesture, affect, comments, and gender. 109 undergraduates in a computer literacy course were randomly assigned to one of the six conditions. The results revealed a significant main effect for agent image on role perception: mentor-like image was perceived as more motivating, as hypothesized. Also, there was a significant main effect for voice: the strong voice was overall most motivating, while both human voices (strong or calm) were perceived as more affable, affective, credible, and facilitating learning than the computer-generated voice. There was no significant effect of agent image and voice on
