We review e orts in de ning design principles and creating tools for building multimodal dialog systems with emphasis on the speech modality. General design principles and challenges are outlined. The focus is on system architecture, application and speech interface design, data collection and evaluation tools. We conclude that modularity, exibility,(More)
In this paper, a dialogue system for natural language based call steering is described and studied. The system is based on natural language speech recognition and understanding within a mixed initiative dialogue. The system is implemented on Bell Labs. Speech Technology Integration Platform (BLSTIP) using dialogue and natural language understanding(More)
This paper describes an embedded Voice Interface Language (VIL) that enables the rapid prototyping and creation of applications requiring a voice interface. It can be integrated into popular script languages such as Perl or Tcl/Tk. Three levels of single-word commands enable the application designers to access basic speech processing technologies, such as(More)
In this paper, we describe a distributed multimodal dialogue system architecture based on the concept of hybrid-VoiceXML. It utilizes a special hybrid-construct to integrate multiple multimedia, multimodal processes into one dialogue that includes VoiceXML as its voice modality. The hybridconstruct in our approach has several important functions. It(More)
