Well… I’m guessing that the data is still unencrypted. Also, why does the audio data need to be converted to text via a server on the web? Modern devices have enough processing power to convert speech to text on their own, without the need for some internet server to do what the product itself was advertised to do. In other words, we don’t need Nuance’s servers for voice recognition: the processor in the TV itself should be fast enough to process it’s own voice commands.
This is little more than an excuse, one that I’m not buying. Just because Big Brother Samsung says “it’s for your benefit”, doesn’t mean their spyware is benign. The only way to make sure they don’t use your shiny new Samsung smart TV to spy on you is to not connect your TV to the internet. That is, of course, assuming you have a Samsung smart TV. If you don’t, good for you. I wouldn’t buy a Samsung TV if they were the last TV manufacturer on earth, at least not until they’ve seen the error of their ways (which they wouldn’t, since they’d have no competition to slow them down).
