© ftw Sep-02 / 3 MONA key topics Feasibility and usability of multi-modal applications in today’s mobile network (computational costs, data rate, latency). Selection and combination of modalities and media for content delivery based on presence information, profiles and terminal capabilities. Integration of speech technologies, such as TTS, ASR and DSR into advanced application frameworks, i.e. the OSA/Parlay architecture.
© ftw Sep-02 / 4 MONA project goals Realization of multi-modal applications based on the experiences gained with the tourist guide application of the ftw. research project „C1 - UMTS Application Development“. Target platforms are PDAs, pocket PCs and Smartphones. Advanced speech services Enhance mobile applications with TTS, ASR and DSR systems as investigated by the ftw. research project „B2 – Speech & More“. Distributed, modular and object oriented design Use the OSA/Parlay based service framework based on the ftw. research project „A1 – Service Platform and Interoperability“. Optimize the solution for mobile networks (GPRS / UMTS).
