The system functionality includes spoken dialogue control of navigation coordinated display of the procedure text display of related pictures alarms and recording and playback of voice notes. The demo also exemplifies several interesting component technologies. Speech recognition and language understanding have been developed using the Open Source REGULUS 2 toolkit. This implements an approach to portable grammar-based language modelling in which all models are derived from a single linguistically motivated unification grammar. Domain-specific CFG language models are produced by first specialising the grammar using an automatic corpus-based method and then compiling the resulting specialised grammars into CFG form. Translation between language centered and domain centered semantic representations is carried out by ALTERF another Open Source toolkit which combines rule-based and corpusbased processing in a transparent way. Astronauts aboard the ISS spend a great deal of their time performing complex procedures. This often involves having one crew member reading the procedure aloud while while the other crew member performs the task an extremely expensive use of astronaut time. The Intelligent Procedure Assistant is designed to provide a cheaper alternative whereby a voice-controlled system navigates through the procedure under the control of the astronaut performing the task. This project has several challenging .
