A Paradigm for Mobile Speech-Centric Services

The work presented in this paper describes a new paradigm for speech interaction on mobile devices. A general framework for a distributed architecture is introduced and described. This is followed by a discussion of how to design multi modal interfaces affording spoken input. The solution has been to create an architecture capable of supporting several alternative GUIs, e.g. with spoken input, stylus input or a combination. Speech GUIs are designed entirely without GUI widgets requiring stylus or button input, instead relying on highlighting parts of text to create emphasis and steer the users' attention. This is exemplified through the presentation of a prototype for a Car Rental application.
