Are these mere coincidences or a result of all the tracking algorithms that tend to follow us all around nowadays? Or are our devices listening to us?
One researcher says, nope, its no coincidence: Your smartphone is definitely listening to everything you say.
Your smartphone spies on you, but maybe not the way you think
Back in the summer of 2018, a reporter for the trực tuyến site Vice conducted an experiment to see if his phone was listening to his conversations.For five days in a row and two times daily, he uttered phrases to his phone and monitored his Facebook feed for changes, specifically for sponsored posts.
He said the changes to his Facebook ad content came literally overnight. He tested phrases like going back to the university and later saw ads for mid-semester university courses,and after he said I need some cheap shirts, he saw ads for cheap apparel.
The Verges article got a lot of press and even inspired more scientific studies to test the secret listening abilities of smartphones.
A group of researchers from Northeastern University tested the theory. They werent able to prove or disprove whether our phones are listening (they found no evidence of recorded conversations), but they make an unexpected finding. Apps installed on smartphones have the ability to record your screen and whatever you type, including user names and passwords.
Your voice triggers smart speakers and smartphones
Your smartphone is similar to smart speakers like the Amazon Echo and Google trang chủ they listen for wake words like Hey Siri and Okay Google all the time.
These wake words are required for your smartphone to actually start recording. But without these triggers, your voice inputs are processed only within your smartphone and are not sent anywhere, so say the manufacturers.
If this temporary voice data is not going anywhere, then whats the problem? In some cases, third-party apps like Facebook or Instagram may still have access to this local data.
So similar to how virtual assistants work, its safe to assume that smartphones listen all the time waiting for the wake word and voice datacontinuously gets recorded, albeit temporarily, on the gadget itself.
Is listening to you without your knowledge legal?
Using voice tracking for marketing purposes is legal because the privacy policies and end-user agreements you agreed with plus current laws actually allow it. Since its a very effective targeted ad tool, its not a surprise if companies are using it.
This app voice-tracking technology is certainly scary, but the thing is,all these companies really care about is effective advertising. Voice triggering is just yet another available tool, similar to browser cookies and location tracking, they utilize to efficiently target ads.
Privacy dangers exist, of course, but for regular folks, this probably shouldnt be a cause for big concern. Who cares if youre looking for fluffy pillows and ultra-soft bedsheets, right?
However, if youre still concerned about this, I dont blame you. Here are ways to turn off your smartphones always-listening abilities:
What to do to make your phone stop listening to you
Disable Hey Siri
Like the Echo, Siri is always attentive, even when youve forgotten your iPhone can hear you. With iOS 8, Apple introduced the Hey Siri wake phrase, so you can summon Siri without even touching your iPhone. If you turn this feature on, this means your iPhones mic is always listening, waiting for the phrase Hey Siri.
Apple says this is processed locally on the device and your iOS device does not start recording your voice until it hears Hey Siri. Once your request is recorded, it then uploads the audio file to Apples servers for processing.
But that may still give you the willies, and luckily, you dont have to disable Siri completely to stop the Hey Siri feature. Heres the easiest way to turn off Hey Siri: Navigate to your iOS devicesSettings>>General>>Siri, thentoggle AllowHey Sirito off.
Disable Ok Google
Google wants more voice-activated tech, and the company recently released its latest masterpiece, OK Google. This serves as Googles new wake phrase, just like Alexa and Hey Siri, calling the attention of Google Assistant on Google trang chủ speakers, Android smartphones, and the Chrome browser.
Every time you use OK Google or use another voice-controlled function, your request is recorded and the snippets are saved to your Google account.
Luckily, Google introduced a new My Account tool that lets you access your recordings and delete them if you want. You can also tell Google to stop recording your voice for good.
Heres how to turn off the OK Google wake phrase: On Android, just go toSettings>>Google>>Search & Now>>Voice and turnOK Googledetection off.
Disable Hey Cortana
Finally, there is Cortana, the voice-activated system from Microsoft. Similar to the others on this list, Cortana can answer questions, do searches, set appointments, and open applications. The wake phrase is Hey Cortana. Just like the others, Cortana has raised some eyebrows.
Heres how to turn off Hey Cortana:Open Cortana on your Windows computer, select the Notebook icon in the right column, click on Settings then toggle Hey Cortana to off.
Disable Facebooks mic access
Although all the evidence supporting the allegations that the Facebook app is listening through your phones microphone for advertising purposes is purely anecdotal, its still your choice if you want to disallow it or any other app from accessing your mic. Its actually quite easy!
If you are an iPhone user, go to Settings >> Facebook >> Settings >> slide the Microphone switch to the left so it turns from green to white. That turns it off.
Alternatively, you can go to Settings >> Privacy >> Microphone >> look for Facebook then do the same. Note that you can toggle the mic on and off for other apps, too.
For Android users: Try Settings >> Applications >> Application Manager >> look for Facebook >> Permissions >> Turn off the mic.
Important: Keep in mind that turning off Facebooks microphone access will affect and disable specific features of the app such as Live Video. If youre going to use these features, you will have to toggle the mic back on.
