Abstract
The Persona system integrates speech recognition, natural language understanding, animation
and speech synthesis to create a conversational assistant that interacts with the user in a spoken
dialogue. A key goal of the system is to allow users maximum flexibility to express their
requests in whatever syntax they find most natural. Therefore, we have chosen to base the
interface on a broad-coverage natural language processing system, even though the assistant
currently understands requests in only a very limited domain. This paper describes the
integration of natural language processing into Persona, indicates why we believe our approach
can be extended to new application domains, and argues that the use of a general purpose natural
language understanding system is a better strategy for conversational interfaces than the creation
of specialized application languages.
