After Amazon's news this week,
I feel the need to share this advice from my Privacy Guides article again:
Notify guests if you are
using a smart speaker
If you are using a smart speaker device in your home such as Amazon's Echo (Alexa), Apple's HomePod (Siri), Google's Nest,
Inform your guests about it when they enter your home 
These devices have the capacity
to record all conversations, and there has already been instances of accidental privacy invasion reported about this 
Even if you don't mind yourself,
offer your guests to UNPLUG your smart speaker while they are visiting you
