Abstract
VoiceXML (Voice Extended Markup Language) has become a major force in interactive voice services. However current approaches to creating Voice-XML services are rather low-level. Graphical representations of VoiceXML are close to the textual form of the language, and do not give a high-level description of a service. CRESS (Chisel Representation Employing Systematic Specification) can be used to give a more abstract, language-independent view of interactive voice services. CRESS is automatically compiled into VoiceXML for implementation, and into LOTOS (Language Of Temporal Ordering Specification) or SDL (Specification and Description Language) for automated analysis. The paper explains how CRESS is translated into VoiceXML and LOTOS.
