Another LG TV owner here
I want to echo what the parent said. LG TVs are decent in general. The voice feature is just a gimmick added to make the company/product look cool. Perhaps it gains some WOWs when demoed in store. But in real life, its voice recognition is subpar, and the feature does not get used much. And yes, you have to press a button on the remote for the TV to listen (via a mic in the remote in my case).
