OpenVXI 2.0 Readme

The OpenVXI is a VoiceXML Interpreter developed by SpeechWorks International, Inc., available as open source to developers worldwide. The OpenVXI provides a key VoiceXML component to all developers who want to add VoiceXML capabilities to their products without developing that technology on their own and therefore, without having to track changes and additions to the VoiceXML standard over time. For companies with VoiceXML platforms, the OpenVXI serves as a reference to ensure that they are executing VoiceXML consistently so they can deliver cross-platform compatibility. As with other open source technologies, developers can take advantage of any subsequent contributions to the OpenVXI made by SpeechWorks or any other developers worldwide. For example, to build a speech browser, developers can take advantage of the SpeechWorks OpenSpeech Browser Platform Integration Kit, based on the OpenVXI. The high-level OpenSpeech Browser Platform architecture is illustrated below.

The OpenVXI is distributed according to the terms of the SpeechWorks Public License.
