just went to google translate, but the pronunciation there is absolutly horrible and gets nowhere close to the actual pronunciation.
And NO, you can't hear the R in german word endings with R, it's always something like AH
I'm German ;) and usually you only hear the R if it's pronounced very clearly. That's why I always told my daughter when she was learning to write, speak clearly. It's spelled Wasser, not Wassa or Vater not Vata. :D
