Recently I had a repairman come to the home to fix an appliance. In communicating he (or I) spoke into his smart phone and then I (or he) read what the other one had said in the appropriate language.
Later at work, a coworker said that police use this frequently in communicating with people who don’t speak English very well (or at all).
Yep. I’m a nurse and we use those language apps to communicate with some of our patients.
