> an app for collaborative voice translation
Tangential, but an idea I've always thought the world needs but I've never seen: an "app" for near-realtime announcements in international airports. You "always" hear announcements for (presumably, but you never know) international persons in countries where the local tongue is not spoken by the intended recipient (is English used as a standard in international airports?) Regardless, it seems to me it would be useful to instead TYPE the text into an app, send it to a translator, and get a properly pronounced audio recording in the person's native tongue to put over the speakers instead of English.
Of course, a missing piece of data is the person's native tongue - presumably the world can't get it's shit together enough to attach that to a person's profile (passport)?, so perhaps make the 1st announcement in English, and if a second one is made then do that as a translated version (or english and translated).
Then again, a likely better (in some cases but not foolproof due to roaming issues) or supplemental approach is sending a text message.
Just curious if you've ever heard of someone trying to do this.
