I work on software that, among other things, runs a call center and I've been getting requests to do something like this in real time so that we can communicate with our users that don't speak english (We have agents who speak other languages but they wanted a fallback for when they weren't there). I told them real-time was still a little bit out (even with this as an API it would take time to integrate). This is really exciting though and I look forward to the day that we can do this will little to no lag and talk to people who don't share a language in common.
