VoiceXML is an emerging standard within the speech industry that holds great potential for widespread acceptance. The ability to allow callers to navigate web sites with their voice, listen to audio content on the web, and eventually combine speech with wireless applications, brings communication to another level. SpeechWorks supports these efforts by adopting a standards-based strategy including open source code to promote market expansion.

This presentation highlights VoiceXML and how developers can take advantage of open source code to build speech applications. Part of the presentation reviews how to build solutions with the OPenVXI VoiceXML interpreter. Other topics include VoiceXML integration with complementary protocols like SIP (Session Initiation Protocol) for call transfers correlated to a data stream using speech links open source code.
