Designing an Enhanced VUI Tree Framework for e- Education System

VoiceXML is a standard language recognized by World Wide Web Consortium (W3C) for developing Voice User Interface (VUI) applications. Advances in speech recognition and VUI systems have motivated the provision of a VUI design framework for interacting with vocal applications. For most developers, designing a VUI is a relatively new experience. Today, good VUI frameworks are few mainly because VUI design is novel and requires usability criteria for users’ friendliness and ease of navigation during interaction. This paper presents an enhanced VUI tree framework for Voice-Enabled E-Education System (VEES) using Multi-RootNode Tree to improve speed of access and user’s flexibility while interacting with the system. The propose system will be of immense benefit to the normal users and the visually impaired learners since it will make navigation, access speed and interaction process with the system a lot easier
