Abstract and Keywords
A spoken language dialogue system is a computational system which engages in multi-turn dialogic interaction with human users using speech as the means of communication. Any system which does this requires many of the capabilities of other natural language processing applications, encompassing both language understanding and language generation; but the nature of spoken language dialogue means that it also poses a number of additional challenges not faced by other applications. This chapter discusses a number of key issues that need to be addressed when attempting to build systems that can engage in natural dialogue, and provides an overview of existing research in these areas.
