AI-powered speech recognition and text-to-speech software can aid learners with disabilities, while intelligent tutoring systems can provide support for those unable to access conventional education.

人工智能语音识别和文本转语音软件可以帮助残疾学习者，而智能辅导系统可以为那些无法接受传统教育的人提供支持。

On top of that, there are people building novel interactive experiences, like smart TVs and intelligent tutoring systems, that respond to hand gestures and emotion.

最重要的是，人们正在构建新颖的交互体验，例如智能电视和智能辅导系统，这些体验可以响应手势和情绪。

Although there are other approaches, intelligent tutoring systems often use Bayesian knowledge tracing to support what’s called mastery learning, where students practice skills, until they’re deeply understood.

尽管还有其他方法，但智能辅导系统通常使用贝叶斯知识追踪来支持所谓的掌握学习，学生练习技能，直到他们被深刻理解。

For that, intelligent tutoring systems build and maintain a student model – one that tracks, among other things, what production rules a student has mastered, and where they still need practice.

为此，智能辅导系统建立并维护一个学生模型——一个跟踪学生掌握了哪些生产规则，以及他们还需要练习的地方。
