VoiceXML is the World Wide Web Consortium’s standard scripting language for creating IVR applications. Plum’s platform software enables the creation of VoiceXML IVR gateways and complete systems. In conjunction with conventional server hardware, Plum’s platform is capable of running VoiceXML applications 24X7X395 reliability. The Plum platform software includes a VoiceXML 2.1 compliant interpreter, support for several speech synthesis and speech recognition engines, developer tools, operations and management utilities, and logging and reporting utilities. The Plum software suite controls a telephony gateway that consists of telephony boards installed in a conventional server running the Linux operating system. The VoiceXML interpreter, which controls the gateway, may tap into modular plug-ins and resources, typically speech recognition engines and text-to-speech engines, to enable advanced telephony functionality. Among other features, VoiceXML 2.1 interpreter includes ECMA Script support, robust DTMF recognition with instantaneous barge-in and response, speech barge-in support, recording support, and configurable support for thousands of separate VoiceXML applications simultaneously.
