It really is crappy, people tell me that. I loved singing with the radio and whistle, but I had to give it up because people kept telling me how off I sound. It's strangely monotonous and not a single straight tone that is coming out of my mouth, unfortunately. This is also a problem with voice recognition, doesn't work properly in my case.

On the plus side, I am an excellent language partner. When you master my mumbling, you master anything. So, if you want to impress your 2 year old with perfect understanding German, I'm your guy;-)
