A:Answer This TV has Google Assistant built in, with Android TV. Pretty much any sound bar will work ok with this TV since it's screen is so large, anything will fit underneath it. No, Alexa compatibility is not a thing. Android TV is pretty poor also. as an example, the picture settings can be set in the home screen, but is not accessible while watching an app, like Netflix. If you can find a Roku TV version, I strongly recommend it. The TV itself is pretty decent otherwise.
