NASA, Xerox to Demonstrate 'Virtual Crew Assistant'

Intelligent conversation with robots - long the bread and butter of science fiction authors - soon may take another step closer to reality for astronauts on the International Space Station.

Scientists from NASA Ames Research Center in California's Silicon Valley and Xerox Corporation (NYSE:XRX - News) will demonstrate a sophisticated, voice-operated computer system on June 26 at the Association for Computational Linguists' 25th annual meeting at the University of Michigan, Ann Arbor. Called Clarissa, the system was developed in an effort to ease astronaut workload
"Clarissa is a fully voice-operated 'virtual crew assistant,' enabling astronauts to be more efficient with their hands and eyes and to give full attention to the task while they navigate through the procedure using spoken commands," said Beth Ann Hockey, project lead on the team that developed Clarissa at NASA Ames.

"NASA wanted the system to be ready to assist at any time and without requiring artificial activation commands," said Renders. "Therefore, a simpler 'Star Trek' solution - like having crew members address the computer by stating a specific word such as 'computer' before posing a question or speaking a command to the system - wasn't a viable solution. We needed to improve the performance of the system in discriminating between commands and conversation."

The technology developed by Renders to address the NASA speech-recognition problem is also being used at Xerox to improve categorization results for printed or digital documents. Xerox researchers at Grenoble have developed a number of leading-edge software capabilities that make it easier for Xerox customers to manage document content.

This significantly increases the system's ability to determine the difference between commands directed to the system and side conversations. According to Renders, the improvements have cut the error rate of the system by more than half.

Clarissa currently supports about 75 individual commands, which can be accessed using a vocabulary of some 260 words. The team plans to increase the commands and add to the vocabulary in the future.
