High-performance spoken dialogue interfaces typically use spoken command grammars, which define what users can say when talking to the underlying systems. For a complex application, the implementation and maintenance of such an interface is a major task requiring specialized expertise in computational linguistics and software engineering. The resulting grammars are difficult to maintain and do not readily port to new domains.

Regulus is an exceptional Open Source toolkit for construction of spoken command grammars. It has been developed since 2001 by a consortium whose main partners are NASA Ames, Geneva University, and Fluency Voice Technology. Grammar development with Regulus uses example-based methods and reusable grammar resources, which reduces the level of expertise needed and makes the process more automated. The Regulus approach is effective for building command grammars even at initial stages of a project, when domain data may be scarce. Regulus has been used to build command grammars for several major projects. Among these are NASA's Clarissa, which in 2005 became the first spoken dialogue system to be deployed in space, and MedSLT, an Open Source medical speech translator developed at Geneva University.

This book presents a complete description of both the practical and theoretical aspects of Regulus, with several application examples that can be downloaded from the companion website.

Manny Rayner is a research scientist at NASA Ames Research Center, California, and Geneva University, Switzerland. Beth Ann Hockey is a research scientist at Ames Research Center. Pierrette Bouillon is project lead on the MedSLT medical spoken language translation project at Geneva University.
