Researchers at the University of Texas at Dallas' Center for Robust Speech Systems (CRSS) are using a 2012 grant from the U.S. National Science Foundation to develop Explore Apollo, a public website featuring audio from the Apollo moon missions.

The team used novel speech-processing techniques to reconstruct and digitally convert thousands of hours of analog recordings from the lunar missions.

After they had transferred the audio from reels to digital files, the researchers needed to create software for detecting speech activity, including tracking each talker and what they said and when. They also had to create algorithms to monitor speaker characteristics to help researchers analyze how people react under tension.

"CRSS has made significant advancements in machine learning and knowledge extraction to assess human interaction for one of the most challenging engineering tasks in the history of mankind," says CRSS director John H.L. Hansen.
