VoiceXML application is set of VXML that can be built dynamically or have static VXMLs which can be fetched by your server application which is developed using Java, Servlets, JSPs, dynamically constructed VXMLs or static VXMLs which are located in some known locations are sent out to a Voice interpreter/voice browser (Normally Media Server), which will parse the VXML received and excutes the VXMLs. The VXML document should start with Header information that conforms XML standard followed by DTD used to validate well formed VXML, and version of VXML used.
Ex: <?xml version="1.0"?>
      <!DOCTYPE vxml PUBLIC "-//W3c/DTD voiceXML 2.0//"EN"                                 
         "http://www.w3.org/TR/voicexml20/vxml.dtd">
      <vxml version="2.0" xmlns="http://www.w3.org/2001/vxml>

The VXMLs can be used to develop IVR application, this application should be integrated with Media Servers, TTS, ASR to uttilise to maximum extent
