LG TVs transcribe conversations you’re having in the room and store them locally. While they haven’t been caught sending that data anywhere AFAIK, there are known vulnerabilities that lets attackers read these transcriptions.

Gamers Nexus had a viral video about them here: https://www.youtube.com/watch?v=6IFVTcM28KA

From what I understood, the TV doesn’t actually do that. It can do that when hacked, but that something else entirely.

		It does do it but LG claim that it is only used to identify activation words for voice control. It has nothing to do with being 'hacked'.
