The goal of the PRINCESS project is the development of a distributed end-to-end multimedia platform prototype. The platform supports access to media servers in a computer network via various types of mobile terminals. New paradigms for user interfaces are applied in order to make the terminal devices more intelligent and to enable hands-free operation for a busy user. A speech recognition module capable of recognising Finnish words has been integrated into the user interface. The vocabulary of command words is continuously restricted and adapted to the part of the user interface under control. The experimental system has been demonstrated in a distributed digital image retrieval application. Several different more conventional user interfaces may be used in the application, but the user may also opt to use a speech driven interface. Experiments show that the use of a dynamic vocabulary greatly reduces the recognition errors as compared to a fill set of command words in our application
