Clarissa, an experimental voice enabled procedure browser that has recently been deployed on the International Space Station (ISS), is to the best of our knowledge the first spoken dialog system in space. This paper gives background on the system and the ISS procedures, then discusses the research developed to address three key problems: grammarbased speech recognition using the Regulus toolkit; SVM based methods for open microphone speech recognition; and robust side-effect free dialogue management for handling undos, corrections and confirmations. . | A Voice Enabled Procedure Browser for the International Space Station Manny Rayner Beth Ann Hockey Nikos Chatzichrisafis Kim Farrell ICSI UCSC RIACS NASA Ames Research Center Moffett Field CA 94035-1000 mrayner@ bahockey@ kfarrell@ Jean-Michel Renders Xerox Research Center Europe 6 chemin de Maupertuis Meylan 38240 France Abstract Clarissa an experimental voice enabled procedure browser that has recently been deployed on the International Space Station ISS is to the best of our knowledge the first spoken dialog system in space.

Crew members usually have to divide their attention between the task and a paper or PDF display of the procedure. In addition since objects float away in microgravity if not fastened down it would be an advantage to be able to keep both eyes and hands on the task. Clarissa an experimental speech enabled procedure navigator Clarissa 2005 is designed to address these problems. The system was deployed on the ISS on January 14 2005 and is scheduled for testing later this year the initial version is equipped with five XML-encoded procedures three for testing water quality and two for space suit maintenance. To the best of our knowledge Clarissa is the first spoken dialogue application in space. The system includes commands for navigation forward back and to arbitrary steps. Other commands include setting alarms and timers recording playing and deleting voice notes opening and .
