    Toggle the physical mute switch

    Locate the microphone-off button on the top or back of your smart speaker. Press the button until a red LED ring or indicator light activates, signaling that the internal microphone circuit is physically disconnected.

    Note: Hardware switches are superior to software settings as they create a physical break in the circuit.

    Disable wake word detection in settings

    Open the companion app for your device. Navigate to Device Settings, select your specific speaker, and look for Microphone or Wake Word options. Toggle the switch to Off to stop the device from actively listening for the wake command.

    Note: Some devices may require a full power cycle for software changes to register.

    Clear your voice interaction history

    In your account privacy settings, locate Voice Activity or History. Select the option to Delete all history or Set auto-delete to Off. This removes stored audio recordings from manufacturer cloud servers.

    Note: Automate this process by setting auto-delete to 3 months if supported by your account settings.

    Disable personalized results

    Access the device settings menu and toggle off Personal Results or Voice Match. This prevents the speaker from identifying individual users, thereby limiting the amount of biometric and behavioral data linked to your identity.

    Isolate the device on a guest network

    Log into your router's administration interface using a web browser. Move your smart speakers to a dedicated Guest Network that does not have access to your primary devices or sensitive local files.

    Note: Ensure AP isolation is enabled on the guest network to prevent speakers from communicating with other IoT devices.
