Looking For NIST 2003 Rich Transcription Exercise (RT-03) Dataset

I need to replicate the below paper in which the dataset in title has been used.

The paper: Goldwater, S., Jurafsky, D., & Manning, C. D. (2010). Which words are hard to recognize? Prosodic, lexical, and disfluency factors that increase speech recognition error rates. Speech Communication, 52(3), 181–200.
