On the VIZIO, which is the most troubling since it’s the only company — that we know of — which spys by default, you can turn off Smart Interactivity by following these steps from your TV.
Press the MENU button on your TV’s remote.
Select Settings.
Highlight Smart Interactivity.
Press RIGHT arrow to change setting to Off.
The other TVs should be safe so long as you have the voice recognition features turned off.
