Somewhat related, my sister was a medical transcriber. For the younger crowd who may not realize what this is, doctors used to dictate their medical notes to tape recordings and the tapes were sent to services that would listen to the tape and type in the notes. So these recordings were full of all kinds of crazy medical terms, drug names, and non-native English speakers with thick accents. My sister could put the tape playback headphone in one ear, type the doctor's notes, and carry on a normal conversation on speakerphone. The whole time she was having the normal conversation, she's typing away medical notes like a madman! It sounded like someone just beating the hell out of a keyboard.
