Very interesting article about VUI Design from Daniel Mecanovic and Hao Shi – School of Computer Science and Mathematics Victoria University, Australia. Voice User Interface (VUI) design is an integral part of developing any VoiceXML telephone application just like a Graphical User Interface (GUI) is very important when designing a visual application. In this PDF document, a series of experiments are conducted in order to understand user experience, improve the initial VUI design and provide valuable information for your future VUI development with VoiceXML.
