Question

One American university used a robot as a teacher to help students with their problems. And none of the students knew that was a robot in the beginning!

Jill Watson, an IBM-designed robot, has been helping graduate students at Georgia Institute of Technology (美國(guó)佐治亞理工大學(xué)) solve problems with their design projects. When answering their questions, Jill seems to be an excellent teacher. She can give wonderful answers quickly. She sounds natural and usually says good words. After 5 months, the students were told that their "teacher" was a robot, and many were shocked.

Now many students like to ask questions on their school's website. It usually takes teachers too much time to answer them. So the university had such an idea of making Jill Watson. It's a faster way to help the students with their problems.

Jill can quickly find possible answers to the questions in her own computer and make sure they are all right. After that, she tells the students in an electronic voice that sounds like a famous actress. She was trained by Georgia Tech researchers before being thrown into the mix with nine other teachers.
