Our washing machine plays a (somewhat annoying) tune, loudly enough for me to hear it from upstairs or the front room, but it shuts up after 5 or 10 seconds.
It also talks to the internet, and I've been finding app control surprisingly useful - I quite like being able to turn it on while I'm out, so that the cycle finishes shortly before I get home, or I can set an extra spin without having to actually go to the kitchen. It's also easier to adjust things like number of rinses or temperature through the app, or at any rate it gives you more options than through the machine's control panel.
