There exists already a pretty useful recognizer for Estonian numerals (Alumäe et al. 2004). There is also a long way to the next stage – full Estonian natural language speech recognizer. At the Rehabilitation Technologies laboratory of TUT we suggest to use this number recognizer to build different limited vocabulary driven but flexible and general enough input and control systems for Disabled Persons. We work in three directions. Disabled persons have often not the best possible pronounciation, so one has to build a system which can work with a lot of background and inner noise. Another direction is to build an agile table-driven 3-layer control system according to Kolmogorov-Vilenkin superposition theorem. We try also to implement a general table-driven interface description system using the finite state machine method and its very effective implementation in J-language. The solutions have to be general enough to handle easily very different disabilities needs and allow such systems not to be so expensive. In our talk we will give an overview and demonstrate our solution prototypes.
