System and method for generating and presenting multi-modal applications from intent-based markup scripts

Abstract

Systems and methods are provided for rendering modality-independent scripts (e.g., intent-based markup scripts) in a multi-modal environment, whereby a user can interact with an application using a plurality of modalities (e.g., speech and GUI) with I/O events being automatically synchronized over the plurality of modalities presented. In one aspect, immediate synchronized rendering of the modality-independent document in each of the supported modalities is provided. In another aspect, deferred rendering and presentation of intent-based scripts to an end user is provided, wherein a speech markup language script (such as a VoiceXML document) is generated from the modality-independent script and rendered (via, e.g., VoiceXML browser) at a later time.
