Automatically subtitling the 31C3

So many great talks at 31C3 this year, but particularly looking forward to this one, especially given the previous discussion at https://news.ycombinator.com/item?id=7829357

It does look like some of the talks at 31C3 are being subtitled in near-real time, it's evident in some cutaways showing a slightly delayed text feed underneath the presentation slides. Really nice to see.
