User application simulation in the evolution of an intelligent speech interface

This paper considers the particular nature of speech interfaces and some of the problems inherent in speech as an interface medium, and it attempts to overcome these problems by improving the interface design. The need for an adaptable interface is identified and the use of models simulating the application and the user is described. Reference is made to a particular project - the Hatfield Polytechnic Intelligent Speech Driven Interface Project (ISDIP) - and the attempts being made to implement such an interface in the context of an intelligent knowledge base.
