This fact was described in Samsung’s privacy policy. They say: “Please be aware that if your spoken words include personal or other sensitive information, that information will be among the data captured and transmitted to a third party through your use of Voice Recognition.” Now, on the 2015 models, the TV is not hearing anything; the listening is done by a microphone built into the remote control and that microphone doesn’t pay attention to the sounds around it unless and until someone hits the “voice” button on the remote. But you need to monitor all the time this button before doing anything linked to your privacy.
