In this paper, we study the approach followed to use the VoiceXML standard in a dialog system platform already available in our group. As VoiceXML interpreter we have chosen OpenVXI, an open source portable solution where we can make the modifications needed to adapt the solution to the characteristics of our recognition and synthesis modules; so we will emphasize the changes that we have had to make in such interpreter. Besides, we review some relevant modules in our platform and their capabilities, highlighting the use of standards in them, as SSML for the text-to-speech system and JSGF for the specification of grammars for recognition. Finally, we discuss several ideas regarding the limitations detected in VoiceXML.
