JVoiceXML Release 0.7.3.GA

JVoiceXML http://jvoicexml.sourceforge.net is a free VoiceXML interpreter
for JAVA with an open architecture for custom extensions. Demo
implementation platforms are supporting JAVA APIs such as JSAPI and JTAPI.

VoiceXML is an implementation of VoiceXML 2.1, the Voice Extensible Markup
Language, specified at http://www.w3.org/TR/voicexml21
as an extension to VoiceXML 2.0, specified at http://www.w3.org/TR/
voicexml20/.
VoiceXML is designed for creating audio dialogs that feature synthesized
speech, digitized audio, recognition of spoken and DTMF key input,
recording of spoken input, telephony, and mixed initiative conversations.
Major goal is to have a platform independent implementation that can be
used for free.
