I am from the Southren United States, and yes I have a light Southren light to my voice, the more excited, angry, worked up I get the thicker it gets. I also use a lot of Southren slang and am in a bad habit of calling people hun. Heh my accent is super thick on certain words like iron (I run) naked (na keed) and I take the ing off words all the time (lightning becomes ligtnin')
