Duolingo首席执行官Luis von Ahn认为AI有很多可以教给我们的东西
首先，她会适应你的水平——我们知道你的水平，因为你一直在Duolingo上学习，所以我们对你的水平有相当清楚的了解。
原始摘录
First of all, she adapts to your level — we know your level because you’ve been learning on Duolingo, so we have a pretty good idea of what your level is.
上下文
我们有一组用户喜爱的角色。其中一个是留着紫色头发、对你很不以为然的emo青少年。你现在可以和她交谈，练习你的对话技巧，并且可以与她进行非常好的对话。关于她有很多令人惊叹的地方。
原始上下文
We have this cast of characters that our users love. One of them is an emo teen with purple hair who is very unimpressed by you. You can talk to her now and practice your conversation skills, and you can have really good conversations with her. There are a lot of things that are amazing about her.
