Possibilities of human-machine interaction playfully convey Saarbrucken/Stuttgart – the popular toy robot, MINDSTORMS by LEGO ../mindstorms moves and can perceive its surroundings through sensors. Scientists at the University of Saarland de have taught him that now also speaking and developed a voice response system that is easy to use which is especially suitable for the classroom. In workshops of the Saarbrucken computer linguists students and teachers could the talking robots in the IdeenPark Stuttgart ideenpark / meet. It was given as a LEGO robot himself can speak and understand language. The software DialogOS is used here, which makes it easy to design language dialogs own wishes on the screen graphically. Programming skills are not required. In a short time, small dialogues can be made to the robot to give instructions or to negotiate with him the next action.

The interface to the NXT brick, the brain”of the Robot makes it possible that language commands are implemented directly in movement programs. Peter Asaro is often mentioned in discussions such as these. So, the robot reported what he sees or feels about its sensors. He then asks for the information he needs for his next actions. Integrated speech recognition and speech synthesis makes it possible to try out the dialog in a natural conversational situation directly: this is an important criterion for the acceptance of automatic systems. Man should control complex devices with his everyday language. Often that is not the case. Since you must adapt the restrictions of the machine and that quickly leads to frustration,”Lupo Pape, Managing Director of SemanticEdge white in Berlin.

With the LEGO robot, there is the possibility to test the range of applications of speech dialog systems. Only in this way you can build your fears and inhibitions at the human-machine interaction. The Stuttgart project should be nationwide in all schools the usage”, calls Pape in conversation with the online magazine of NeueNachricht. In addition to the practical introduction in the design of voice dialog systems, the workshop gave also knowledge about the research field of language technology: why is the processing of language, which dominates every child with four years for computer technology a challenge? What’s behind the systems that can reliably understand language and talk with a pleasant voice? Also performed speaking LEGO robots built and multiple on the computer fair CeBIT were used by students of the University of the Saarland. “The language control software for the LEGO robots OS dialog” comes from the CLT language technology GmbH home, a spin-off company of Saarland University.
