In this paper we present an approach to embedding VoiceXML applications by an off-line compilation scheme. Our primary motivation is that while VoiceXML is an established standard for voice applications, the complexity and resource requirements of VoiceXML interpretation have so far limited its spread to application areas other than telephony-based services. In many contexts, such as ubiquitous computing, being able to embed voice applications into a larger framework is more important than the dynamic creation of VoiceXML documents that makes the processing particularly resource demanding. For these environments, we propose off-line VoiceXML compilation into ECMAScript as a solution for reducing the resource demands, thus making VoiceXML a viable option for the many small devices that replace the desktop in ubiquitous computing. We also describe our portable Java-based run-time platform that makes it possible to run a complete spoken language dialogue system on any computer supporting Java.
