It has no problems in understanding me either as I am a native speaker aswell.
Though I must admit I love asking random questions and changing the accent from German, French, Scottish, Arabic and even Indian. The results are entertaining.
I wish that they change this soon though. It sucks not be able to get answers when asking for locations here in Switzerland.
On another note, anyone tried saying Zürich? She always comes back saying, " I do not know what Xeric is "? Cant shake the Züri- Deutsch accent.
