The Museum of African Diaspora has an online exhibit called Slave Narratives that features audio clips of former slave stories.  The site features a short biography about the individual and a personal account of what it felt like to be a slave.  You can either listen to the account online or read the transcript online.

If you are interested in this topic also check out “Excerpts from Slave Narratives” from Steven Mintz at the University of Houston or Narrative of the Life of Frederick Douglass from the Berkeley Digital Library.
