Google is promoting its new Home smart speaker as a way to access Google's knowledge — hands free.

Home will be able to perform many of the same tasks as Echo, Amazon's internet-connected speaker. Both will use voice commands to play music, field questions and control home appliances — assuming you've installed "smart" versions of them.

If you're feeling creepy about a speaker listening to your conversations, Google says you can turn the microphone off.

Home will be available on Nov. 4 for about $130, with advance orders starting Tuesday. The cylinder-shaped Echo costs $180, though Amazon also sells a smaller version shaped like a hockey puck that sells for $50.
