Virtual Assistants Rely on Voice Data – But Aren‘t Always Spying
Let‘s start by understanding why companies like Amazon, Google, Apple, and others enable their virtual assistants with voice recording capabilities in the first place.
At their core, assistants like Alexa and Siri need to collect and analyze snippets of your speech in order to understand requests and provide accurate responses. This voice data allows them to continuously improve voice recognition abilities and the overall AI behind the scenes.
According to their own privacy policies, these snippets are anonymized so they aren‘t tied directly to your identity or account. Only a small fraction of short recordings may be reviewed by internal teams to help train the machines and algorithms powering your smart speaker.
Now, it‘s true that some independent security researchers have found these devices accidentally recording private conversations at times. Bloomberg reported that Amazon employees listened to Alexa recordings that should have been private. And a study by AppCensus found that ultrasonic signals could trigger Alexa and Google Home devices without using wake words in some cases.
While the chances of your device spying on you are very low, I recognize these reports may still cause unease about how and when virtual assistants are listening to you. The good news is you can take charge of your privacy settings based on your comfort level.
Mythbusting: Common Concerns About Always-On Listening
Before going into how to adjust settings, let‘s mythbust some of the most frequent assumptions people have around smart speakers and 24/7 eavesdropping:
Myth: Virtual assistants are recording everything you say and uploading it to company servers.
Fact: There is no strong evidence to suggest these devices are recording conversations outside of wake word detection. The companies that make them claim privacy is taken very seriously during product development.
Myth: The purpose of listening is to gather more data to sell you products.
Fact: Companies like Amazon and Google already have troves of consumer data like shopping habits and browsing history. It‘s unlikely they are that desperate for snippets of audio without context.
Myth: Hackers could access microphone data and my private conversations.
Fact: Remote access of mics would require highly sophisticated hacking that is likely beyond the means of most malicious actors out there. However, someone who gained physical access to your devices could potentially hack the microphones locally.
Myth: Devices are always listening even when not in use.
Fact: Virtual assistants rely on local speech recognition to detect wake words. When not activated, it‘s very unlikely they are transmitting audio back to company servers.
Myth: My conversations are being recorded and saved forever.
Fact: Recordings are temporarily saved to improve voice recognition. But companies like Amazon and Google let you delete these recordings at any time.
Hopefully dispelling some of those myths provides peace of mind. Next I‘ll walk you through step-by-step how to limit microphone access and recordings.
How to Stop Alexa From Listening to You
If you want to ensure your Alexa-enabled devices like the Amazon Echo aren‘t recording you, there are a few straightforward ways to disable the microphone entirely or delete recordings:
Mute Alexa‘s Microphone
This instantly cuts off the microphone access:
- Press the microphone button on top of your Echo device. A red light indicates Alexa can no longer hear you.
Delete All Alexa Recordings
Purging past recordings ensures they aren‘t stored on Amazon servers:
- In the Alexa app, tap into Settings > Alexa Privacy > Review Voice History.
- Select all recordings and choose Delete Selected Recordings. This wipes them permanently.
Enable Deletion by Voice
You can also command Alexa to delete daily recordings by enabling this option:
- In the Alexa app, go to Alexa Privacy > Manage Your Alexa Data.
- Under Voice Recordings, toggle on Enable Deletion by Voice.
- Going forward, you can say "Alexa, delete everything I said today" and recordings will be deleted.
Opt Out of Alexa Recordings
If you want to disable recording altogether:
- In the Alexa app, go to Alexa Privacy > Manage Your Alexa Data.
- Choose Don‘t Save Recordings and toggle Use of Voice Recordings off.
Just know this may degrade Alexa‘s ability to understand you according to Amazon.
Preventing Google Assistant From Listening In
For Google Home users, you have a couple options to stop Assistant from listening and linking recordings to your account:
Turn Off Voice & Audio Activity
On your computer:
- Visit myactivity.google.com and click Settings.
- Go to Activity Controls and uncheck Include audio recordings.
In the Google Home app:
- Tap your profile icon > My Activity > Web & App Activity.
- Uncheck the box for Include voice and audio activity.
Fully Disable "Hey Google" Activation
You can also completely disable the wake words like "Hey Google" that trigger recording:
- In the Google Home app, tap your profile icon > Settings > Assistant.
- Toggle Hey Google detection off.
Mute Microphone on Google Home Devices
For instant microphone disabling, press the mic mute button on the back of your Google Home speaker. The LED lights will turn orange to indicate the mic is off.
How to Stop Siri From Listening on Apple Devices
Over in the Apple ecosystem, you have a couple quick options to limit Siri‘s eavesdropping abilities:
Turn Off Siri on Apple TV
Via your Apple TV settings:
- Go to Settings > General > Siri History.
- Select Delete Siri & Dictation History to wipe recordings.
Disable Siri Completely on HomePod
On your HomePod:
- Open the Home app and tap into your HomePod‘s settings.
- Choose Siri History and select Delete Siri History.
Disable "Hey Siri" on iPhone
To fully turn off hands-free Siri access on your iPhone:
- Go to Settings > Siri & Search.
- Toggle Listen for Hey Siri and Press for Siri off.
Beyond Assistants: Additional Ways to Protect Privacy
Adjusting virtual assistant settings is a great first step. But there are a few other smart ways you can proactively safeguard privacy:
Use Encrypted Messaging Apps
When communicating sensitive info, use secure apps like Signal or WhatsApp that encrypt messages end-to-end by default.
Turn On Two-Factor Authentication
Add an extra login step like biometrics or a security code to prevent password comprised. Require 2FA on important accounts like email, financial, and social media.
Browse Anonymously with a VPN
A VPN like ExpressVPN masks your IP address and encrypts data to prevent snooping. This lets you browse and access content privately without being tracked.
Limit App Permissions
Be diligent about only enabling location, microphone, contacts and calendar access when needed to prevent unnecessary data gathering.
Disable Fingerprint Unlocking
Fingerprints can be replicated. Stick to secure passcodes or facial recognition for phones and laptops when possible.
Use Antivirus Software
Stay protected against malware, viruses and other cyberthreats that could jeopardize your personal data.
Always-On Listening Concerns and Risks
I‘ll wrap up with some final thoughts on the risks posed by always-on listening capabilities in virtual assistants even though companies downplay them:
-
Accidental Triggers: As seen in research studies, ultrasonic signals or TV audio can sometimes trigger recording without wake words.
-
Internal Access: Amazon and Apple have teams that manually review a small subset of recordings, which does present a privacy vulnerability.
-
External Hacking: Remote takeover of mics would require high sophistication, but physical access hacks are more feasible.
-
Data Leaks: Recordings could potentially be exposed in a breach, especially if anonymization fails.
-
Tracking: Voice profiles combined with other data points make it easier for companies to build detailed behavioral profiles.
So while the chances of always-on listening remain low, I advise taking precautions based on your personal privacy preferences. You may also consider physically unplugging devices when not in use as an added safeguard.
The Bottom Line
I hope this insider guide gave you a comprehensive overview of how virtual assistants work, debunked some myths, and most importantly empowered you to adjust settings to disable recording and limit data access. While Alexa, Siri and others provide great conveniences, you ultimately have control over your privacy. Finding the right balance is key so you can enjoy the benefits while still protecting personal information.
