Any App to dynamically create subtitles in real time

Hi folks
I recently got a Manhattan "Freely" puck box which is brilliant -- and what seems great is that some subtitles are generated in real time while you are watching if you want subtitles. For example there's a channel called Talking Pictures TV which has really old classic TV and movies from the earlier days of TV and cinema long before things like subtitles were even heard of - and it's a tiny very niche channel so wouldn't have the staff or resources to create / licence etc subtitle creation so there must be some sort of A.I in the Manhattan Freely box generating these. To turn off simply press the subtitle button on the handset.

To anybody buying these though -- one slight flaw -- there's no SKY NEWS app on this -- not sure why or maybe an update is coming but the puck is brilliant if you want to watch all local UK available terrestial channels for ZILCH ( inc the huge archive on BBC iPlayer) -- although how that doesn't get in problems with UK TV licensing authority -- no idea -- "don't ask don't tell;" !!!wherever you are on the planet without a need either for using a VPN.

I'll be testing this in China (Shanghai) in a couple of weeks as I'm visiting for a while -- it works in the USA as I've already tried it there in Santa Monica CA.

Cheers
