Can voice assistants be private, or do they record everything?

✓ Accepted answer

Voice assistants can be configured to significantly limit data collection, but they do have continuous listening capabilities by default that users can disable or restrict.

• Disable Continuous Listening: Most major platforms, including Amazon Alexa and Google Assistant, allow users to turn off the "always on" microphone feature. When enabled, the device listens for specific wake words; when disabled, it only processes voice commands when a physical button or screen is explicitly activated. This setting is found in the dedicated apps under security and privacy settings.
• Review and Delete History: All recorded interactions are stored on company servers for a period ranging from one week to an infinite duration, depending on user settings. Caregivers should regularly log into the provider’s app to review and delete voice clips. Both Microsoft and Apple offer features to automatically delete recordings after 30 days, a setting worth enabling for older adults.
• Use Physical Mutes: Hardware microphones can be physically disconnected or covered when not in use. Some newer devices feature a hardware mute switch that cuts power to the microphone entirely, providing the highest level of security. This is particularly useful during sensitive family conversations.
• Check Data Sharing Policies: Before purchase, review the specific privacy policy of the chosen assistant. Organizations like the Electronic Privacy Information Center (EPIC) publish guides on how different companies handle voice data. Ensure the company does not share audio recordings with third-party advertisers unless explicitly opted in.
• Secure Wi-Fi Networks: Ensure the home Wi-Fi network uses strong, unique passwords and WPA3 encryption. This prevents local attackers from intercepting voice data as it travels from the device to the cloud. A hardware firewall can add an extra layer of protection for connected medical devices.
