It would be cool if every time you pick up your phone, the system tells you a reminder like
"You are speaking fluent Tagalog, in a chirpy, femenine voice"
This is annoying because sometimes I forget to change my main language or my @voice and people don't recognize me, I have to change it after the fact and it just looks a bit tacky from an IC perspective that you speak the wrong language when you mean to speak another language.
