VXI* VoiceXML

The VXI* VoiceXML browser for Asterisk® gives operators and solution providers the ability to rapidly develop and deploy innovative voice and video applications via IP, PSTN, and 3G-324M networks. VXI* is fully compliant with the W3C's VoiceXML 2.0+ specification and is integrated with automatic speech recognition (ASR) and text-to-speech (TTS) software to enable advanced voice and video solutions, and real-time video calling applications. VXI* can be installed in common hardware configurations, providing a highly scalable base system to meet all customers' business and technical VoiceXML requirements.

VXI* VoiceXML interpreter works directly with the Asterisk® PBX software supported by Digium®. Not only can users of the open source PBX run VoiceXML applications in the same server, they can now offer these powerful, scalable IVR / IVVR solutions at an affordable cost.
