Looks like there is a small difference as voice search and voice activation.

I own smart tv (Sony) that has microphone on the remote which you can only use at Youtube search bar (then light lit on the remote when microphone is active), and I believe it's quite nifty as typing via remote is PITA.

On the other hand I don't know voice activation features on smart TVs. Do you tell your TV to "turn on" or "change channel", which is not practical IMHO.

It makes sense that personal assistants (amazon echo, apple siri, google whatever) listen all the time as you use trigger words to activate them but it's so useless for TVs.
