VoiceXML and the W3C speech interface framework
J.A. Larson · IEEE Multimedia · 2003
VoiceXML is a markup language for creating voice-user interfaces. It uses speech and telephone touchtone recognition for input and prerecorded audio and text-to-speech synthesis (TTS) for output. It's based on the World Wide Web Consortium's (W3C's) Extensible Markup Language (XML) and leverages the Web paradigm for application development and deployment. By having a common language, application developers, platform vendors, and tool providers all can benefit from code portability and reuse. The paper discusses VoiceXML and the W3C speech interface framework.
