Looks like Samsung TVs too have a trigger word that can be changed, (and the whole voice recognition can be turned off) see settings: http://youtu.be/arsAs9pGr

Looks like Samsung TVs too have a trigger word that can be changed, (and the whole voice recognition can be turned off) see settings: http://youtu.be/arsAs9pGrBk?t=52s http://youtu.be/arsAs9pGrBk?t=52s I don't know for sure that the tigger word is processed locally on SmartTVs too, but it's likely because Samsung said: 'voice data is provided to a third party during a requested voice command search', so you have to request it's happening probably with the trigger word. And technically it would not make too much sense to constantly stream audio from every SmartTV because the trigger word recognition is a simple enough task to do it locally and also the continuous stream would consume lot of bandwidth for the users and probably for the servers too. But it's still very concerning that we have more and more devices with microphones and internet connections and in the case of SmartTVs proprietary OS with questionable security.
