What do you mean? I use it every day for playing music, making calls while in the car, set alarms and timers; it's by far the quickest way to set a reminder. And I'm using it in Italian.
every other town / region has its own words in Germany. people can tell when i use Siri cuz no one would actually talk / write among friends like that as in "proper german" lol OR siri simply doesnt understand what i am trying to say. I cant use it for music either cuz it never gets english words / artists right when i tell it to play english songs while being set to german
