How to stop your devices from listening to (and saving) everything you say
Yes, voice technology is amazing. You can ask your phone a question. You can talk to your speaker system and book an Uber. With the right setup, your voice can lock the doors, dim the lights and change the thermostat. All across America, people are embracing their oral fixation.
But while virtual assistants are handy, they’re always listening. As more manufacturers and developers jump onto the audio tracking bandwagon, you may wonder how much your devices are recording. And what happens to the audio files they gather?
Worst of all are the apps that use ultrasonic data to profile you. You don’t hear the tones, but your device does. (More about that later.) Some regular apps are designed to spy and report back recordings. Click here for five spy apps that could be watching and listening on your phone right now.
Creeped out? Lots of consumers don’t trust their virtual assistants and wonder how to switch them off. If you’re worried about the privacy risks of your smartphone’s always-on microphone, here are tips for turning it off.
When you install the Facebook app on your phone, it asks for access to your microphone. Why? Because Facebook needs to record your voice when you shoot live video. But some people are wary of this. Does the app record you only when you’re on camera? Or is Facebook “listening” to you all the time?
Facebook denies it’s always listening — and there’s no evidence that it is — but you are absolutely welcome to sever the tie between app and microphone. Many people have no use for this access anyway, so there’s nothing to lose by switching it off.
If you are an iPhone user, go to Settings >> Facebook and 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, then look for Facebook and 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.
If you decide to shoot video later on, just return to those settings and re-establish the connection to your mic. You can switch it off again when you’re done.
Is Amazon Echo always listening? Alexa is activated when it detects one of its wake words: “Alexa,” “Amazon,” “Computer” or “Echo.” You’ll know the device is ready for a command when the outer ring at the top glows blue. But before that happens, Alexa always has open ears, waiting to be addressed.
When activated, Alexa allows you to search the web, play music and control smart home devices you’ve added to your home network. For example, with the right smart gadgets, you can turn off the lights in another room, lock the front door, turn up the thermostat, etc.
The downside is that Amazon keeps an audio recording on its servers of every voice command you give to Alexa, along with a fraction of a second of audio before the wake word. The recording ends after the command has been processed.
I was surprised when I checked my Amazon Echo recordings. In one recording, I was explaining why I wasn’t taking a deal on a commercial building that I had for sale. You should take a moment and check your recordings. Click here to learn how to hear all your Amazon Echo recordings, and how delete them too.
Like the Echo, Siri is always attentive, even when you’ve 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 iPhone’s mic is always listening, waiting for the phrase “Hey Siri.”
Apple says this is processed locally on your iOS device, and it does not start recording until it hears “Hey Siri.” Once your request is recorded, it uploads the audio file to Apple’s servers for processing.
But that may still give you the willies. Luckily, you don’t have to disable Siri completely to stop the “Hey Siri” feature. Here’s the easiest way to turn off “Hey Siri”: Navigate to your iOS device’s Settings >> Siri & Search, then toggle off “Allow Siri When Locked.”
Google recently released its latest masterpiece, “OK Google,” the wake prompt for Google Assistant on Google Home speakers, Android smartphones and the Chrome browser.
