Cross modality adaptation of service front ends

The current evolution of pervasive technologies means that traditional access modalities are not always suitable for a particular service and, consequently, need to be reassessed. There are many scenarios in which the user is unable to use a screen or keyboard to interact with a given service. In such cases, a vocal interaction can be useful, but this is only supported by a few application providers. We propose a solution to adapt existing Service Front Ends in order to support vocal interaction, which is based on reverse engineering, adaptation heuristics and automatic generation of the vocal implementation.
