Automatic speech grammar generation during conceptual modelling of virtual environments

Lode Vanacken, Chris Raymaekers, Karin Coninx
2008 The Visual Computer  
In this paper, we introduce an approach to automatically generate a speech grammar which is generated using semantic information.  ...  Speech interfaces are becoming more and more popular as a means to interact with virtual environments but the development and integration of these interfaces is usually still ad-hoc, especially the speech  ...  Speech interfaces are increasingly being used in virtual environment applications since this way of interacting allows for more flexible and natural forms of interaction within a virtual environment.  ...
