SALT LAKE CITY — As Elizabeth Smart prepares to release a book about her experience, she is giving a new glimpse into her kidnapping nightmare.
Smart spoke to NBC's Meredith Vieira about the abduction and the horrible crimes committed against her 11 years ago.
She said she was a slave to Wanda Barzee and an object to Brian David Mitchell.
Smart said she "didn't feel human" during her nine months in captivity.
"I mean, here I was, a 14-year-old girl, ripped from my family, from my friends, from the people I loved," she said. "Being raped every day, not knowing when I'd be able to eat next, not knowing when I'd be able to drink next, and being chained to a tree."
"What does that do to a child?" Vieira asked.
"I don't think there's anything worse you can do to a child," Smart responded.
The interview airs Friday night on KSL TV.
Smart's memoir, "My Story," will be released next week.
Smart was abducted from her Salt Lake City bedroom in June 2002. Brian David Mitchell and his wife Wanda Barzee kept her tethered at a makeshift campsite, then took her to California.
The trio returned to Utah, where Smart was recognized and returned to her family.

Mitchell is serving a life sentence and Barzee is serving 15 years to life in connection with the crime.
Since the abduction, Smart has gone on to create a foundation that helps to prevent crimes against children.
She's also served a full-time LDS mission in Paris, graduated from college and gotten married.
