口型模拟技术及其在网络课程中的应用探索

Exploration on Mouth Shape Simulation and Its Application in Web Course

口型模拟是一种人工智能技术，目前已在多个领域得到应用。文章在介绍口型模拟技术的基础上，比较了两款典型软件的特点，并探讨了该技术在网络课程制作中的应用。通过实验证明，在网络课程中采用口型模拟技术生成动画来讲解理论性知识，与真实教师视频讲解的教学效果基本接近，二者在测验成绩和认知负荷方面未呈现显著差异。

Mouth shape simulation (MSS) is a kind of artificial intelligence technology， and it has been applied in many areas at present. This paper introduces the technology and compares two typical pieces of software of MSS. And it explores the application of MSS in the development of web course. From a contrast experiment， the result shows that there are no significant differences on test scores and cognitive load between two experimental groups. That is， the learning effect of the experimental group which used MSS is similar to the one which used real instruction video in some instructions on theoretical contents.
