If you own a Smart TV from Samsung you might want to be careful as to what you are saying because its listening to you if you sport a voice activated TV at home or anywhere for that matter.But its not like Samsung have not warned you already as Stated in its privacy policy which can be read in full here
Voice Recognition
You can control your SmartTV, and use many of its features, with voice commands.
If you enable Voice Recognition, you can interact with your Smart TV using your voice. To provide you the Voice Recognition feature, some voice commands may be transmitted (along with information about your device, including device identifiers) to a third-party service that converts speech to text or to the extent necessary to provide the Voice Recognition features to you. In addition, Samsung may collect and your device may capture voice commands and associated texts so that we can provide you with Voice Recognition features and evaluate and improve the features. 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.
If you do not enable Voice Recognition, you will not be able to use interactive voice recognition features, although you may be able to control your TV using certain predefined voice commands. While Samsung will not collect your spoken word, Samsung may still collect associated texts and other usage data so that we can evaluate the performance of the feature and improve it.
You may disable Voice Recognition data collection at any time by visiting the “settings” menu. However, this may prevent you from using all of the Voice Recognition features.
In a report today from the BBC Samsung warns its customers not to have conversations in front of the TV but Samsung have responded with the following.
It said the privacy policy was an attempt to be transparent with owners in order to help them make informed choices about whether to use some features on its Smart TV sets, adding that it took consumer privacy “very seriously”.
Samsung said: “If a consumer consents and uses the voice recognition feature, voice data is provided to a third party during a requested voice command search. At that time, the voice data is sent to a server, which searches for the requested content then returns the desired content to the TV.”
It added that it did not retain voice data or sell the audio being captured. Smart-TV owners would always know if voice activation was turned on because a microphone icon would be visible on the screen, it said.
