What kind of accent do you have?
A Dutch one. You know instantly when a Dutch person speaks English.
For example a D at the end of a word is pronounced as T in my language. In English cart and card are pronounced diferenty, for us we pronounce it the same way :p
We also don't have a 'th' sound, so we pronounce it as a D.
Stuff like that :p
Neutral American -- I'm from Michigan. Which gets weird when people here ask what accent I have and I'm like "...I don't... HAVE an accent."
Technically, you do. You're just so accustomed to hearing yourself that it would sound weird for somebody to say that you sound different.
