eMobility – Strategic Applications AgendaHealth and InclusionNameDistributed Speech Recognition (DSR)DescriptionClient/server architecture with recognition mainly carried out by a remote server. Recognitionfeatures are extracted at the client side, compressed and transmitted to the server, whererecognition is performed. Advantages over an embedded speech recognition system:oooooUse of simple clients.It frees the user of upgrading and maintenance tasks.It allows easy language portability.Smaller bit-rate.Increased robustness.UtilisationThese services will be a requirement for impaired people. Speech enabled services will be arequirement for some types of users such as blind people or ageing people with sight difficulties.Due to the type of disability, an oral interface is the best way to interact with the application.ComponentsSpeechCharacteristicsMaximum transfer delay: 250 msRobust to high loss rate swith short burst length. More sensible to long bursts lengths.RequirementsA mobile device with the DSR client implemented.TrafficIt has low bit-rate requirements.EntitiesBlind organizations, ageing people with sight difficulties.Technical CharacteristicsTime dependencyTime-based.Delivery requirementsReal time.Symmetry of the connectionAsymmetric.Bit rateLow bit rate, constant.Maximum transfer delay250 msII.
