I use my voice to get a lot done. Siri sets meetings for me, silences my phone, and lots more. Tap or click for five simple voice commands you’ll use all the time.

An Amazon Echo can help you find your phone, lock the front door and drop in to chat with loved ones. Tap or click for the things I always ask Alexa to help with.

What’s the downside of always-on devices that listen for commands? Nearly all voice-activated technology uses microphones that listen for "wake words." That means they are, technically, always listening.

If you want to take control of your privacy, here’s how to stop your smart devices from listening.

Foiling Facebook

Facebook sometimes requests access to the microphone for video chatting and text-to-speech purposes. You might not feel comfortable giving Facebook control of your mic. You can follow these steps for any app you want to block mic access to.

Note: There are many Android manufacturers, so the steps outlined in this article may differ from your model. If so, check with your model’s online manual. 

For iPhone:

• Open the Settings app. Then, scroll down and tap Facebook.
• Toggle the green switch next to Microphone to the off position.

You can also follow these steps:

• Open the Settings app. Then, scroll down and tap Privacy & Security.
• Locate the menu labeled Microphone and tap it.
• Find Facebook in the list of apps and toggle the green switch to the off position.

For Android:

• Open the Settings app, then tap Apps.
• Tap the app you want to change, in this case Facebook.
• Choose Permissions. To change a permission setting, tap it, then choose from these options: Allow only while using the app, Ask every time, or Don't allow.

If you decide to shoot a video or chat with a friend, return to these settings and enable your mic. You can always switch it off again when you’re finished.

Stopping voice assistants

It is common knowledge that virtual assistants can pick up snippets of private conversations if you say something that sounds like the wake word. One study outlined 1,000 phrases that tripped up Alexa, Siri, Cortana and Google.

If you’re worried about your gadget’s always-on microphone, here are the steps to turn it off. Just know you’re trading some convenience for privacy.

Amazon Echo

• On your Echo device, find the button that looks like a microphone or a circle with a line through it.
• Push the button. This stops the device from passing voltage through the mic’s internals.
• If you wish to use Alexa, simply press the button again. You can always turn the mic off when not in use or during a private conversation.

Siri

• Open the Settings app on your iPhone. Scroll down and tap Siri & Search.
• Toggle the green switch next to "Listen for ‘Hey Siri’" to the off position.
• You can also turn off Allow Siri When Locked to prevent Siri from activating if a button is pressed in your pocket.
