In the last bimester, we have focussed our work on with the refinement and testing of the Service Prototype and Demonstrator, (Deliverable 3.1) which is part of the Task 3: System Development, Implementation, Integration and Testing. Specifically, we have completed the interface to the MS dictation engine, in preparation to a refinement of the ASR process, that relies on both a recognition based on a language model specified using an application dependent grammar and a generic language model. We have adopted and specialized the dialog infrastructure offered by the Speaky Mediavoice development environment and we have thus delivered a new version of the prototype system. We have run some tests on the VUI, and we have collected the results obtained by processing a small corpus of spoken sentences. The analysis of these results has been used in order to define possible improvements of the prototype.
