Dan
Hello and welcome to 6 Minute English. I'm Dan.

Rob
And I'm Rob. So Dan what's… Oh, sorry. Oh, it's my wife. Err… hang on…

Dan
You didn't answer!

Rob
Don't take this personally, Dan, but I'm not exactly crazy about someone eavesdropping on my phone call. If you eavesdrop on something, you secretly listen to someone's conversation. Some things are private, you know?

Dan
Oh! Of course! I totally understand. One quick question for you though… do you have a smart speaker? You know, like the Google Assistant, Amazon's Alexa or Apple's Siri.

Rob
Oh sure, yes, I've got one! It's great! I can ask it all sorts of questions, it tells me about the news and weather, it plays music when I want… it does all sorts! You just give it a voice command and it does what you want!

Dan
So it can hear you, can it?

Rob
Of course! How else can you give it a voice command?

Dan
All the time?

Rob
Well, I assume so.

Dan
So how do you know it's not eavesdropping on you?

Rob
Well, I… oh… I see. I hadn't thought of that.

Dan
That's our topic for this 6 Minute English. How safe is your smart speaker? However, before that, here's our quiz question. By what percentage has the number of smart speakers used in US households increased from December 2017 to December 2018? Is it…

a)    around 40%
b)    around 60%, or
c)    around 80%?

Rob
Oh, well, I know they are very popular even in my household. So I'm going to go for c) around 80%.

Dan
We'll find out if you're right later in the programme. So, smart speakers and privacy! Florian Schaub is an assistant professor at the University of Michigan School of Information. Here he is speaking on the BBC World Service programme The Why Factor about smart speakers. What does he say people are introducing into their homes?

Florian Schaub 
You're basically introducing... listening bug in your home, in your most intimate space. While the companies say they are only actively listening to what's going on in your home when they hear the keyword, the microphone is still on the whole time in order to be able to detect that keyword. We don't know to what extent companies are co-operating with the government or to what extent the government might try to circumvent company security mechanisms in order to then be able to listen to what you're doing.

Dan
So what did he say people are introducing, Rob?

Rob
He basically said we're introducing a listening bug. Now, a bug is a small electronic device used for secretly listening to conversations. Much like a spy would use.

Dan
Yes, and he mentioned it was in our most intimate space! Intimate means 'private and personal'.

Rob
Well, I can't think of anywhere more intimate than my home. 

Dan
Indeed! He also said that the smart speaker's microphone is on the whole time – even though the companies insist that they're only actively listening when the keyword is said. 

Rob
Yes, he suggested that we can't know how far a company might be co-operating with a government to eavesdrop on people. 

Dan
Or whether a government might be circumventing a smart speaker's security and listening in anyway without the company's or owner's permission!

Rob
Circumvent means 'cleverly bypass or go around'. So if all this eavesdropping is possible, why are smart speakers so popular? 

Dan
Good question! And here's Florian Schaub again with an answer. He conducted a study on people's attitudes to privacy when it comes to smart speakers. How do people feel about having a smart speaker that could eavesdrop on them? 

Florian Schaub
What we often saw is people just being resigned to 'this is the trade-off they have to make' if they want to enjoy the convenience that a smart speaker provides to them. 

Rob
He said that people are resigned to the privacy trade-off. If you are resigned to something, you accept something unpleasant that can't be changed. 

Dan
Yes and a trade-off is a compromise. You accept something bad to also receive something good. 

Rob
So people accept that a smart speaker gives them advantages, even though there could be downsides? 

Dan
Yes. In the grand scheme of things, the data that these devices hear is probably not that significant considering all the data companies have about us already anyway! 

Rob
So can I have the answer to the quiz then? 

Dan
Of course! Earlier I asked by what percentage the number of smart speakers used in US households increased from December 2017 to December 2018? Was it…

a)    around 40%
b)    around 60%, or
c)    around 80%? 

What did you say, Rob? 

Rob
I said c) around 80%. 

Dan
And you are right. The answer is around 80% - from 66 million in December 2017 to 118 million in December 2018, and around ten million people in the UK now use one too! I guess they're really not worried about eavesdropping

Rob
Nice slide into the vocabulary there, Dan. If someone eavesdrops on you, it means they secretly listen to your conversation. 

Dan
They could be eavesdropping on you through a bug, which is a small electronic device used to secretly listen to conversations. 

Rob
Yes, they may have bugged your most intimate, or private and personal, spaces. 

Dan
Next we had circumvent. If you circumvent something, such as security, you cleverly or bypass it or go around it.

Rob
Then we had resigned. If you are resigned to something, it means you accept something unpleasant that can't be changed. 

Dan
And lastly, we had trade-off. A trade-off is a compromise. You get something good, but you also get something bad. 

Rob
Right - like 6 Minute English! A great discussion and vocabulary, but the trade-off is it only lasts six minutes! 

Dan
Which is just about now, actually - time to go. So until next time, find us all over the place online and on social media. Just search for BBC Learning English. Bye for now. 

Rob
Goodbye!
