6月16日CNN聽力：喬治亞科技學院研發奇異背心 狗狗穿上後可以或許和人類無停滯交換
Our producers use each day's transcript page atCNNStudentNews.com to find "Roll Call" schools.
On Wednesday's transcript, we found Marian MiddleSchool.
They're watching from the nation of India in the cityof Bangalore.
Next to the U.S. East Coast, where the Redcoats arewatching from Berlin High School.
It's in Berlin, the center of Connecticut.
And in southern Georgia, we make a stop in the city of Hahira where the Vikings are watching atHahira Middle School.
If dogs could speak, well, some would have bigger vocabularies than others.
There's a project at Georgia Tech University that fits dogs with a special vest.
The vest has a number of sensors on it.
And the dogs are trained to bite or pull or touch one of the sensors with their noses and thenthat particular sensor triggers a voice that speaks what's going on.
There could be applications for guide dogs, hearing dogs, search and rescue dogs that coulduse a signal to point out a specific problem.
But what is the training process looks like.
Teaching dogs to speak.
We're developing a technology that allows dogs to create message.
This research is really about allowing dogs to talk.
One of my very best researchers is my border collie Sky.
Hey, buddy.
He can say anything we give him the capability to say, so he can tell me the difference betweenwhat toys I'm holding.
What's this?
That is a ball.
He can tell the difference between what sound he just heard.
I hear the doorbell.
He can summon help with a medical alert vest.
We put the vest on him.
I showed it to him once and in 27 seconds later, he knew how to activate the sensor.
The longest that any of our dogs to understand the technology was 28 minutes.
Any dog that's trainable would be able to do this kind of activation because they are based onthings that dogs naturally do.
